thermal equlibrium

Thermal equlibrium is a state in which there is no net flow of heat between two objects

Ok,,there are few things i want to share with you;

THERMAL CONTACT

When a stone is dropped into a beaker of hot water,they come into into thermal contact with each other.

HEAT TRANSFER

As the temperature of water is higher than the stone,the rate of heat transfer from water to stone is greater than the the rate of transfer from stone to water

As a result,there is a net flow of heat from water to stone.Water loses heat and becomes cooler while stone gains heat and becomes hotter.

REACH THERMAL EQULIBRIUM

After some time,the temperature of water is the same with the stone.

However,the transfer of heat still take place but the rate of heat transfer from water to stone and vice versa is the same.

This mean that there is no net flow of heat between them.

Then,the stone and the water are said to be in thermal equlibrium.
