Thermodynamics is essentially how heat energy transfers from one substance to another. In “Joe Science vs. the Water Heater,” the temperature of water in a water heater must be found without measuring the water directly from the water heater. This problem was translated to the lab by providing heated water, fish bowl thermometers, styrofoam cups, and all other instruments found in the lab. The thermometer only reaches 45 degrees celsius; therefore, thermodynamic equations need to be applied in
foundation in thermodynamics. How they interact can be applied to mechanics and experiments. For example, if you add heat to a piston, the gas contained inside will begin to expand and cause displacement, doing work. Gases are heavily studied in thermodynamics, because the internal energy is easier to account for. Gases only have kinetic energy because the potential energy is negligible since the far apart molecules cannot interact with each other. The four main types of thermodynamic processes- isovolumetric
The Difference in Energy Release of Various Alcohols In this experiment, I plan to find out the difference in energy release between different sorts of alcohols. To do this I will test how much alcohol is required to increase the temperature of 100ml of water by 30 degrees Celsius. Obviously, many factors may affect my results, therefore making them less reliable. To improve my results, I will carry out some preliminary research to see if I can improve the reliability and accuracy. Please
Thermal protection is a method of detecting over-temperature conditions and disconnecting the electrical power. This usually used to prevent fires or damage to electronics power supplies and equipment which may arise from the high temperatures. Temperature in power supplies rises due to both environmental factors as well as heat generated by the components themselves. There is heat from semiconductors such as transistors, ICs, switching devices, from transformers, inductors and resistors. The amount
The word thermodynamics is derived from the Greek words therme, meaning heat and dunamis, meaning power. Thermodynamics is a branch of physics that studies the effects of changes in temperature, pressure, and volume on systems at the macroscopic scale by studying the motion of their particles. A system is the subject of study. Heat means energy in transit and dynamics relates to movement of particles; thus, in essence thermodynamics studies the movement of energy and how energy instills movement
The Physics of the Pressure Cooker Generally, water boils at 100 degree Celsius (212 degree Fahrenheit) in normal room temperature and pressure. If somebody boils the water for five minutes or for twenty minutes, the temperature will always remain the same. The pressure of air affects the boiling point of water. If air pressure is changed, then the boiling point will also change according to it (How does”). This is why a pressure cooker cooks food quickly as the pressure of the steam in the
Today I am here to discuss a topic with you but I don’t know where to start. If I ask you, "Is Money a Prerequisite for Happiness?", how would you answer? Your answer should be NO. Definitely NO. But is this truly what you believe? Is this consistent with how you act? All of us want to make money to gain some status, some comfort and some luxurious. This money has brought; is bringing; and will bring so many differences between some of you and me. These differences will be later named as
Thermodynamic Properties of Solid Solutions in the System Ag2S – Ag2Se 1. Introduction This paper is about the calculation of standard thermodynamic properties of the four solid solutions in the phase diagram of Ag2S – Ag2Se. They calculated these properties using the model of regular and subregular solutions. The four solid solutions are: a restricted fcc solid solution (γ- Ag2S-Ag2S1-xSe (x<0.3)), a complete bcc solid solution (β- Ag2S – Ag2Se), monoclinic solid solution (α) from Ag2S to

\Input Variable Outcome Variable Temperature Time taken for the sugar to dissolve Volume of Water Number of Stirs Amount of Sugar Type of Sugar The input variable we are testing is the temperature to see if the time taken for the sugar to dissolve differs. Prediction I predict that when the temperature of the water increases, the time taken for the sugar to dissolve in the water will be quicker than dissolving at a low temperature. This is because, the particles in
Investigating the Temperature at Which Soap Powder Will Perform Best At Introduction I am going to conduct an experiment in the controlled environment of a laboratory. The experiment will consist of placing a stained piece of fabric into water with a fixed concentration of a biological washing powder (Wizzo) in it. I will try this experiment several times trying different temperatured water and leaving the it for a fixed period of time to find the best possible temperature that the Wizzo
PURPOSE The purpose of the experiment is to determine the temperature, in degrees Celsius, at which all particle motion stops (absolute zero). MATERIALS Before assembling the materials, put on safety glasses FIRST, then prepare a clean, dry workspace (away from food) with all of the necessary materials. 1/8 cup water small pan of ice water 1 empty aluminum soda can Tongs or oven mitt Borosilicate glass beaker (600 mL) #1, 1-hole rubber stopper 6”
Even though, there are higher heat temperatures surrounding the ice, its temperature doesn’t change in a solid state. Rudolf Clausius, a German physicist and mathematician, born in 1822, would further develop Mr. Carnot theory of heat and motion. He introduced strict principles of the second law of thermodynamics, which explains that the internal state of a system, in this case the ice cube, and the external state, the water
filled Sadi with great excitement as he had plan to develop a theory for steam engines. Once he returned to Paris he began immediatley working on the mathematical theory of heat. This lead to the start of the modern theory of what we know today as thermodynamics. Sadi's first piece that he worked on was a mathematical expression for the work done by one kilogram of steam. This research done my Sadi was never published to the public. It wasn't until later that Sadi finally published something on his works
The objective of this study was to determine how temperature affects the activity level of the Cepaea nemoralis. Both experiments showed the same relative trend of increased movement in a warm environment as opposed to decreased movement in a cold environment. Both trials had a much greater mean distance travelled over one minute in the warm environment than they did in the cold environment. However, many snails displayed no activity in the cold environment by retracting into their shells and whenever
incoming fresh air. The fresh air relies upon a blower, air induction system, to propel it into the combustion chamber. During this time period the piston begins to travel to the top of the cylinder and compress the fresh air sufficient to raise the temperature in the combustion chamber, (area between the top of the cylinder and the cylinder head at top dead center), to 1000-1200 degrees Fahrenheit (p12 Dagel). The fuel is then injected under pressure into the combustion chamber, the air ignites the fuel
Determination of thermodynamic values allows for analysis of what makes a reaction spontaneous. In this experiment, the equilibrium constant of the crystallization of potassium nitrate as it ionized in water was found and used to determine enthalpy, entropy, and Gibb’s Free Energy of a reaction. The variables were found by by graphing the solubility of potassium nitrate as a function of time and by utilizing relationships based on the van’t Hoff equation. Based on the determined Ksp of 43.4 the
The topic is thermodynamics the meaning of thermodynamics is “the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy) and by extension of the relationships between all forms of energy.” Thermodynamics consist of four laws those four laws being the zeroth law, the first law, the second law and the third law. The zeroth law is “thermodynamic equilibrium and temperature.” the first law is “work, heat, and
combined first and second law of thermodynamics commonly known as availability analysis or exergy analysis is particularly suited for achieving more efficient resource use since it enables the locations, types and true magnitudes of waste and loss to be determined. This information is quite helpful for the design of thermal systems, for directing the efforts to reduce the sources of inefficiency in the existing systems and evaluate system economics. [1, 2 & 3]. In thermodynamics, exergy is defined as the
