Answer: When the particles lose heat they move more slowly and have a decrease in kinetic energy.
Heat is a <u>form of energy</u> that is manifested by an <u>increase in temperature</u> and comes from the transformation of other energies. <u>Heat is caused by the vibratory movements of atoms and molecules that make up bodies or substances</u>. Specifically, for physics, heat is a type of energy that is transferred from one system to another, a transfer that is linked to the <u>disordered movement of molecules, atoms and other particles</u>. In this way, when losing heat, the particles lose energy in the form of kinetic energy, so they begin to vibrate and move slower.
