Question

when heat is transferred by direct contact (conduction), what happens as the heat moves from the warmer substance to the cooler substance? the particles in the cooler substance move faster and faster as it gains heat the particles in the cooler substance move slower and slower as it gains heat

Explanation:

Heat transfer by conduction involves the transfer of thermal energy from a warmer to a cooler substance. When the cooler substance gains heat, its particles gain kinetic energy and move faster.

Answer:

the particles in the cooler substance move faster and faster as it gains heat
