ways by which people live their lives or how society behaves. Some characteristics of the culture of people or a society are their music, food, laws, arts, marriage, festivals among others. Ghana is the first sub-Saharan African nation to gain its independence from the British in 1957. It is located in West Africa and it consists of different ethnic groups with different dialects. One such group is the Ga-Adangbe tribe. The Ga-Adangbe tribe constitutes of the Adangbe and the Ga people of Ghana who
Fuel For A Paintball Marker The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown
breathing in the human body. The gas law, Charles’ Law, demonstrates the relationship between a contained volume of gas and its temperature, a directly proportional relationship. It states that in a contained space, if a gas’ temperature were to increase, the volume of the gas would increase as well (Colbert, et al., 2012). Charles’ Law is confirmed every day inside and outside a hospital, and it is especially important to understand when working with the human body. Most people, at one time or another,
The two articles, As the World Burns and Why Bother, both discuss the challenges of what individuals faced with trying to help stop global warming. In Why Bother, the author explains why one individual would not want to bother changing the climate change, if the entire universe is not going to change as well. However, in As the World Burns, one of the little girls is trying to persuade her friend to go greenhouse friendly but the friend doesn’t by any of what her friend is trying to tell her. The
racks * Gas Syringe (200ml) * Stop Clock [IMAGE] [IMAGE]Method: In a preliminary study, I found the best way for me to do this experiment is by measuring 10ml of distilled water into a measuring cylinder, and mixing glucose solution and yeast suspension. I am going to keep the volume and concentration of the glucose and yeast the same, but the only factor I am going to change is the temperature. Then we put the bung on to the test tube leading to the gas syringe.
John Harte is an ecologist from the University of California at Berkley. He is trying to find out whether heat stimulates further trace-gas from solid or not. He is going to conduct an experiment that will tell him if the greenhouse effect could start a cycle that would cause the effects to be worse than already predicted. The experiment will begin December of 1996 and will run for no less than three years. Harte has stretched a twelve foot high grid of cables above 300 square yards of land
Rate of Reaction Using Enzymes In this bit of coursework I will be investigating the rate of reaction in which enzymes are the catalyst breaking down a substrate. The substrate I am going to use is Hydrogen Peroxide (H2O2, water with another Oxygen), this molecule usually breaks down on its own accord, but also the rate of decomposition can be increased with the use of a catalyst; in this case the catalyst is a biological one called an enzyme. Hydrogen Peroxide slowly breaks down on its
Science Rocket Experiment By : Julia Sánchez Background Information: This experiment is about firing a rocket, we are creating hydrogen gas. We had to fill the bottle with hydrogen gas and then put a flame under the bottle and measure how much it flew upwards. To do this we mixed magnesium strips into hydrochloric acid. A combustion reaction takes place in this experiment. The investigation topic is about the fuel that makes a space rocket fire. A combustion reaction is more known as burning
was and still is a very important person. He received an honorary degree from the University of Oxford. He was also elected into the Royal Society of London and of Edinburgh. He was very well known when he was alive. After his passing, over 40,000 people showed up to his funeral. His contributions to science were so important that without them we would not be technologically where we are today. Works Cited “Dalton, John (1766-1844)”. Wolfram Research. 2007.

scientific method, Joseph Louis Gay-Lussac earns the title of a great scientist. He was born on December 6, 1778 and he was the oldest child. His father was Antoine Gay. He was a lawyer who called himself Gay-Lussac to be apart from all of the other people with the same last name as Gay there. He got that name from the name of some family property near St Leonard(4) . The French Revolution affected the French scientists then. Gay-Lussac was sent to Paris when he was fourteen when his father was arrested
to each shown in (Figure 1). When Benzene was first discovered it was called hydrocarbon. The chemical that we now call Benzene was discovered in 1825 by Michael Faraday. Michael Faraday discovered Benzene from an oily film that deposited from the gas used for lighting. Benzene has a great effect on the environment and health though exposure and effects may vary depending on the life style of a person. The physical properties and chemical properties are essential to a chemical compound, these
down hydrogen peroxide because hydrogen peroxide is poisonous and is a product when the liver breaks down waste therefore enzymes (catalase) must be made in order to deal with it. When the enzyme catalase is added to hydrogen peroxide, oxygen gas is

Nozzle A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In nozzle velocity of fluid increases on the expense of its pressure energy with decreasing pressure. Nozzle have many types and each of them has special uses. The nozzle types are high velocity, propelling
storage tank, hot oil expansion drum, hot oil circulation pumps and hot oil heater. Hot oil is first circulated by Hot Oil Circulation Pumps (P-1301A/B) through Hot Oil Heater (H-1301) where temperature of hot oil rises to 135°C. Low-pressure (LP) fuel gas is used in burners of hot oil heater. The hot oil outlet temperature of H-1301 is controlled by adjusting heater burner firing. From hot oil heater the hot oil is passed through column reboilers, providing the required heat duty and then back to the
non-linear partial differential equations that describes the spatiotemporal evolution of a fluid (gas). Both equations are derived from conservative principles and they model the behavior of some macroscopic variables namely: mass density, velocity and temperature. The evolution of a fluid (gas) can also be described by the exact dynamics of the individual particles that constitutes the fluid (gas) in terms of Newton equations. However, this is complicated in the sense that in order to compute the
This number can be used to determine the thermal conductivity of gases at high temperature and it also delivers us the information about the thickness of thermal and hydrodynamic boundary layer. 2.5 Reynolds Number In fluid mechanics, the dimensionless quantity, fraction of inertial forces to viscous forces, is known as Reynolds Number. Reynolds number can be shown as ,
The oven serves to control the temperature of the column within a few tenths of a degree to conduct precise work. The oven can be operated in two manners: isothermal programming or temperature programming. In isothermal programming, the temperature of the column is held constant throughout the entire separation. The optimum column temperature for isothermal operation is about the middle point of the boiling range of the sample. However, isothermal programming works best only if the boiling point
that the aerosol can is quite a complex container. An aerosol is not a simple cleaner or polish; it is a colloidal system. That means it consists of finely divided liquid or solid particles, called a product, dispersed in and surrounded by a gas. The most commonly used gases, or propellants, are chlorinated hydrocarbons, butane, propane, isobutane, vinyl chloride, and nitrogen. Nitrogen is used particularly for products when the taste or smell of the propellant is not desired in the product
Investigation Into the Effect of Temperature On the Rate of Respiration of Yeast Preliminary Work For my preliminary work, I am working with 35ml of yeast. I think that this is the best volume to use as it is about ¾ of a test tube full, and it allows for the yeasts expansion when heated. I am trying to find out the best range of temperatures to be used in finding out the respiration of the yeast, and I am also trying to find an equilibration time that can be used in the main experiment
