RELATION BETWEEN TEMPERATURE AND KINETIC ENERGY. 

Aim: To establish the relationship between temperature and average kinetic energy. 

Apparatus: Two bowls, food colour, cold water, hot water. 

Procedure: 

1. Take two bowls one with hot water and second with cold water. 

2. Gently sprinkle food colour on the surface of the water in both bowls. 

Observations: 

1. We will observethe jiggling of grains of food colour in hotwater is more when compared to jiggling in cold water. 

Explanation: 

1. We know kinetic energy depends on speed motion of particles. 

2. So the kinetic energy of hotter bodyis greater than that of colder body. 

3. Thus the temperature of a body is an indicator of average kinetic energy of molecules of that body. 

Conclusion: 

 Therefore Average kinetic energy of molecules is directly proportional to absolute temperature.
