multiple choice question
while the word temperature is commonly used to describe how hot or cold something is, in terms of the kinetic molecular theory, temperature is

the measure of the average kinetic energy of the molecules in a substance
the measure of the total potential energy of a substance
directly related to the size of an object
the same as heat

Explanation:

According to the kinetic molecular theory, temperature is a measure of the average kinetic energy of the molecules in a substance. Heat is the transfer of thermal energy, and temperature is not the same as heat. Potential energy is related to the position or state of molecules (e.g., in phase changes, not the general measure of temperature). Also, temperature is not directly related to the size of an object (e.g., a small cup of boiling water and a large pot of boiling water have the same temperature).

Answer:

the measure of the average kinetic energy of the molecules in a substance
