Ixchelt burns her tongue when she takes a sip of hot coffee from her mug. which part of this example represents heat?

This question comes along with four answer choices:

a) the thermal energy moving from the coffee to her tongue

b) the thermal energy moving from her tongue to the coffee

c) her coffee

d) her tongue

a) the thermal energy moving from the coffee to her tongue.

Explanation:

Heat, heat energy and thermal energy are terms to refer the same thing.

Heat is the kinetic energy of the molecules or particles in a substance wich is transferred from hot substances to cool substances.

In the example, the coffe is hot and Ixchelt's tongue is cool, so the heat is the thermal energy transferred from the hot coffe to Ixtchel's tongue.

The thermal energy (heat) always flows from the hot to the cold, never the other way around.
