multiple-choice question
define heat
a measure of how hot something is
a measure of how cold something is
the transfer of energy by thermal interactions

Explanation:

To define heat, we analyze the options:

• "A measure of how hot something is" and "A measure of how cold something is" describe temperature, not heat.
• Heat is defined as the transfer of energy due to thermal interactions (like conduction, convection, radiation). So the correct option is the third one.

Answer:

C. the transfer of energy by thermal interactions (assuming the third option is labeled C; if not, the option "the transfer of energy by thermal interactions")
