Heat flows from a hotter body to cooler body?

That's correct! Heat always flows from a hotter body to a cooler body. This is a fundamental principle of thermodynamics, known as the second law of thermodynamics .

Dit is waarom:

* Temperature is a measure of the average kinetic energy of the particles in a substance. Hotter objects have particles moving faster on average, while cooler objects have particles moving slower.

* Heat is the transfer of thermal energy. When two objects of different temperatures are in contact, the faster-moving particles in the hotter object collide with the slower-moving particles in the cooler object.

* This collision causes energy to be transferred from the hotter object to the cooler object, increasing the average kinetic energy of the cooler object and decreasing the average kinetic energy of the hotter object.

This process continues until both objects reach thermal equilibrium, meaning they have the same temperature.
