The purpose of experiment is to review the physical concepts and relationships associated with the flow of heat in and out of materials by determining the specific heat of the specific materials in the temperature range between boiling water and room temperature water. by doing so, we will come to a deeper understanding of the principle of conservation of energy as it applies to thermal equilibrium principle.

Calorimetry

Explanation:

 In the calorimetry experiments, mix a known amount of a high temperature material, about 100 ° C, with an equivalent amount of water at room temperature. In a device thermally isolated from the environment, and the initial and final temperatures of liquid and solid are analyzed and energy conservation relationships, the specific heat of the unknown material can be found.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
