How can thermal energy be transferred from one object to another if the objects are not in contact?

How can thermal energy be transferred from one object to another if the objects are not in contact?

Radiation is the transfer of thermal energy from one object to another by electromagnetic waves. Radiation does not require a medium through which to travel. Therefore, radiation can occur through matter or via a vacuum.

What is it called when thermal energy moves from one object to another?

The term conduction refers to the transfer of energy. Conduction occurs when energy is passed between objects. The transfer of thermal energy is called heat. Particles of matter are in constant motion. Sometimes they collide with other particles.

Is the movement of heat between objects that are touching?

Conduction is heat transfer between two objects that are touching each other. When two objects touch and one has a higher temperature than the other; heat is transferred to the object with the lower temperature. When you touch something hot it feels hot because heat is being transferred from the object to your hand.

Why does heat travel fastest in gases?

The expansion of the gases and liquids is because the particles are moving around very fast when they are heated and are able to move further apart so they take up more room. If the gas or liquid is heated in a closed container, the particles collide with the sides of the container, and this causes pressure.
