Question

Heat the water in one beaker to 90°c
and other to 60°C. Mix the water with
these beakers? What will be the temperature of mixtures

Answer 1

The temperature of the mixture will be 75 degree Celsius

This is because

According to Thermal equilibrium

The mixture having the highest temperature will try to equalise its temperature when it is mixed in a beaker of water which has less temperature

so this is called thermal equilibrium.

In this process some heat from a high temperature body will be transferred to less temperate body..

so at 75 degree clesius the heat is balanced i.e.

Thermal equilibrium
