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.

Explanation:

Heat transfer occurs from a higher - temperature source (fire) to a lower - temperature substance (water). Fire is hotter than water, and thermal energy in the form of heat moves from the fire to the water, causing the water to boil. Heat energy is not created from air thermal energy (violates conservation of energy), and heat does not transfer from water to fire as water is cooler. Also, the main source of heat here is the fire, not the surrounding air.

Answer:

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