Lab Report Making an Object Buoyant by Adding Extra Volume to Displace the Water Necessary
Ships do not sink because of displacement; the ship moves more water than the ship actually weighs.
Archimedes Principle: Any object wholly or partly immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.
Density is mass of a unit volume of a material substance, expressed as kilograms per cubic meter in MKS or SI units. Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density, while the volume is equal to the mass divided by the density. The weight of a body, which is usually of more practical interest than its mass, can be obtained by multiplying the mass by the acceleration of gravity. Tables that list the weight per unit volume of substances are also available; this quantity has various titles, such as weight density, specific weight, or unit weight. D = mass/volume
Displacement is distance moved by a particle or body in a specific direction. It is a vector quantity, possessing both magnitude and direction. The distance traveled by the point depends on the path that it follows; it will be equal to the magnitude of the displacement only if the path is straight. In mechanics, it is frequently necessary to distinguish between the distance that a point moves--or through which a force acts--and the displacement of the point or the force.
The purpose of this experiment was to make an object buoyant by adding a sufficient amount of extra volume to displace the water necessary.
My hypothesis was that the additional amount of displacement needed would be .54 liters. The needed amount of displacement was found by first finding the difference between the mass and displacement. The solution was the difference in mass and the weight of the water being moved. This solution was divided by the density of the salt water at Seaquarium, which was 1.03 kilograms.
The materials that were needed to conduct this experiment was a concrete or lead object, a scale to weigh the object, string, empty bottles, sea water, a graduated cylinder for measuring the water accurately, and buckets filled with sea water.
The procedure followed to perform the experimentation is as follows:
1. Choose a concrete or lead object and weigh it on a scale.
Sink or Float Introduction: I am doing this experiment to find the density of aluminum foil to see if it floats or sinks when placed in water. I hope to find out how the density of aluminum foil changes when weight is added to the foil. I hypothesize that the boat will hold 20 pennies before sinking. You will need to get: Aluminum foil Pennies Water And a big container or tub for your boat to float in. Procedure: 1.
Theory of Water of Displacement: A volume of water was measured. A second volume of water was measured when the metal cylinder was added. The initial volume was subtracted from the second (total) volume to get the volume of the metal cylinder.
Apparatus: See attached. The water level in the cellulose bag rose because of the higher
time. Then the sand was sunk. Once I had all my apparatus set up I was ready to start the experiment, I had a results table ready to fill in as the experiment. was being carried out by the. Once I had finished each distance I repeated it.
cylinder with water and putting it in a water bath so I can record how
* I will record the temperature of where the experiment will take place * I will record the readings from the burette every 30 seconds for 5 minutes * The experiment will be repeated and the potato chips will be cut into thinner pieces each time, in order to see the effect of the surface area on the volume of oxygen Obtaining Evidence = ==
Purpose: To gain an understanding of the physical property of density. To gain skill in measurement of mass and volume, in addition to the construction of graphs and the physical interpretation of slope.
Measuring cylinder to measure small amounts of fluids. Pipette to gather small amounts of fluids. Test tube holder to hold test tubes. 2. Molar Salt solutions to submerge potato chips in.
To investigate the relationship between the air pressure in a ball and the bounce height of that ball where the drop height (gravitational potential energy), temperature and location are kept constant.
To set up a model for this experiment first of all I have to make a
Two or more forces acting on a body in different directions may balance, producing a state of equilibrium. For example, the downward force of gravity (see gravitation) on a person weighing 200 lb (91 km) when standing on the ground is balanced by an equivalent upward force exerted by the earth on the person's feet. If the person were to fall into a deep hole, then the upward force would no longer be acting and the unbalanced force of gravity would accelerate the person downward. If a body is not completely rigid, then force acting on it may change its size or shape. Scientists study the strength of materials to anticipate how a given material may behave under the influence of various types of force.
Density is how much mass is in a certain volume. You can calculate density by dividing mass by volume. Water's density depends on its temperature and salinity. Cold water with a high salinity is more dense than warm water with a low salinity.
This experiment is designed to educate proper techniques for using an analytical balance and volumetric apparatus’s. Accuracy in volume measurements are significant in analytical chemistry but all volumetric glassware have errors and obscurities linked with the measurements observed. Miniscule damage in a glassware due to aging, abuse and chemicals can create systematic errors in the observational measurements. Volumetric pipets and burets can be used for fairly accurate measurements if they’re standardized correctly. The purpose of this exercise is to measure volume and mass, to evaluate precision of the measurements, and to use the data to calculate the density or standard deviation. This experiment is achieved by first weighing the mass of a coin, mass of weighing paper and then measure both objects together to obtain the average mass of a coin. Following the introduction of calibrating with an analytical balance, we are given the volume of water to transfer into an Erlenmeyer flask or beaker by pipet/buret to obtain the actual volume delivered using the density of water at the given temperature. The process will be repeated three times for each given volume of water. Correspondingly, I will assess the error in the ability to read the glassware accurately by calculating a combined standard deviation of the total mass of the coin, the tolerance level for each volume delivered of water, and the density of water.
The materials that an object is made out of depends on whether or not it floats, not its weight. Does it float or sink? POE Does it float or sink? POE Can you make it float?
