Question

Which best explains why water boils in a pot sitting over fire?

Heat energy is created from the thermal energy in the air.
Heat energy is transferred from the water to the fire.
Thermal energy from the fire moves to the water in the form of heat.
Thermal energy from the surrounding air moves to the water.

Answer 1

Answer: Thermal energy from the fire moves to the water in the form of heat.

Because according to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects
