Heat always travels between two objects from the object with higher temperature to the object with lower temperature. This is because heat is a form of energy, and energy naturally flows from areas of higher concentration to areas of lower concentration.

There are three main ways this heat transfer can occur:

* Conduction: This involves the transfer of heat through direct contact between molecules. For example, when you touch a hot stove, heat is transferred from the stove to your hand through conduction.

* Convection: This involves the transfer of heat through the movement of fluids (liquids and gases). For example, convection currents in the atmosphere cause warm air to rise and cool air to sink, creating weather patterns.

* Radiation: This involves the transfer of heat through electromagnetic waves. For example, the sun's heat reaches Earth through radiation.

It's important to remember that these modes of heat transfer often work together. For instance, when you boil water on a stove, heat is transferred to the pot by conduction, then to the water by convection, and finally to the surrounding air by both convection and radiation.
