Multiple Choice
Which of the following best describes what temperature measures?
A
The total amount of heat contained in a substance
B
The mass of the particles in a substance
C
The average kinetic energy of the particles in a substance
D
The rate at which a chemical reaction occurs
Verified step by step guidance1
Understand that temperature is a physical quantity related to the motion of particles in a substance.
Recall that heat is the total energy transferred due to temperature difference, not the temperature itself.
Recognize that the mass of particles does not define temperature; rather, temperature depends on how fast particles move on average.
Know that the rate of a chemical reaction is influenced by temperature but is not what temperature measures.
Conclude that temperature measures the average kinetic energy of the particles in a substance, reflecting how energetically they move.
