How do you find the specific heat of a metal experiment?
How do you find the specific heat of a metal experiment?
Use Q = sm∆T to determine the heat capacity of the metal. (Make sure to use the heat given off by the metal, the mass of the metal, and the temperature change of the metal in this calculation.)
What is experimental specific heat?
The specific heat of a substance is the heat capacity per unit mass. Thus, heat capacity = mass x specific heat. In this experiment, a heated solid of known mass and temperature is dropped in the calorimeter containing known mass of cold water. The equilibrium temperature is then measured.
Which materials have a specific heat higher than water?
On a mass basis hydrogen gas has more than three times the specific heat as water under normal laboratory conditions.
How is the specific heat of a metal calculated?
A sample of each metal was massed and then heated in a hot water bath. The hot metal was then poured into a known quantity of water in a calorimeter. The amount of heat gained by the water was calculated. The heat gained by the water is equal to the heat lost by the metal.
How does the specific heat test experiment work?
However, this experiment is not time sensitive so depending on the conditions, data can be reordered at multiple different intervals. Data was continuously recorded until the temperature of the substance started to drop indicating that the highest possible temperature was achieved.
What is the purpose of specific and latent heat?
The purpose of this lab experiment is to measure the specific heat capacity of unknown metal samples and also to determine the latent heat of fusion of water.
Why did they test the specific heat of aluminum?
The purpose of this lab was to test and verify the specific heat of a metal. The students heated aluminum in order to understand and observe the specific heat equation in motion in a calorimeter.
