1.	What is the measure of thermal equilibrium? How do you prove? (OR) How do you prove temperature is the measure of thermal equilibrium? (OR) Explain thermal equilibrium with an activity.
Answer» Procedure : Take two glass tumblers and fill one of them with hot water and another with cold water. Explanation & Observation : 1) When we place a thermometer inside the hot water the mercury level of thermometer rises from initial position due to heat transferred from hotter body (hot water) to colder body (mercury in thermometer). 2) When we place the thermometer inside the cold water the mercury level comes down from its initial position due to transfer of heat from mercury (hotter body) to water (colder body). Conclusion : Heat is a form of energy that flows from a body at higher temperature to a body at lower temperature until the temperature remains same for two bodies that is called thermal equilibrium. In the above case, the steadiness of mercury column shows that thermal equilibrium is achieved. That reading of mercury column gives temperature. Thus temperature is a measure of thermal equilibrium.

Procedure :

Take two glass tumblers and fill one of them with hot water and another with cold water.

Explanation & Observation :

1) When we place a thermometer inside the hot water the mercury level of thermometer rises from initial position due to heat transferred from hotter body (hot water) to colder body (mercury in thermometer).

2) When we place the thermometer inside the cold water the mercury level comes down from its initial position due to transfer of heat from mercury (hotter body) to water (colder body).

Conclusion :

Heat is a form of energy that flows from a body at higher temperature to a body at lower temperature until the temperature remains same for two bodies that is called thermal equilibrium.
In the above case, the steadiness of mercury column shows that thermal equilibrium is achieved. That reading of mercury column gives temperature.
Thus temperature is a measure of thermal equilibrium.

What is the measure of thermal equilibrium? How do you prove? (OR) How do you prove temperature is the measure of thermal equilibrium? (OR) Explain thermal equilibrium with an activity.
