Two Objects In Thermal Equilibrium

In summary, thermal equilibrium is a state where two objects are at the same temperature and there is no net flow of heat between them. Factors that affect thermal equilibrium include temperature, thermal properties, surface area, distance, and external heat sources. To determine if two objects are in thermal equilibrium, their temperatures can be measured or they can be touched to see if they feel the same temperature. The law of thermal equilibrium states that if two objects are in thermal equilibrium with a third object, then they are also in thermal equilibrium with each other. Thermal equilibrium is important for understanding heat transfer and plays a crucial role in various physical and chemical processes.

Hello everyone,

I was wondering, is there any way of calculating the time it takes for two objects in thermal contact to come to thermal equilibrium?

Yes. It involves solving the transient heat conduction equation, which is a partial differential equation.
