Answer 1

Thermal energy is transferred from the warmer substance to the cooler substance.

Answer 2

When two substances with different temperatures come into contact, thermal energy is transferred from the warmer substance to the cooler substance. This process is known as heat transfer. The transfer of thermal energy occurs until the two substances reach thermal equilibrium, which means they have the same temperature. The energy transfer is driven by the difference in temperature between the two substances. The warmer substance has higher thermal energy, and during contact, some of this energy is transferred to the cooler substance, causing its temperature to increase. At the same time, the temperature of the warmer substance decreases as it loses some thermal energy. This heat transfer continues until both substances reach the same temperature.
