Question

1. which is measured using a calorimeter? (1 point)

changes in kinetic energy
changes in temperature
changes in potential energy
changes in thermal energy

Explanation:

A calorimeter is an instrument used to measure heat (thermal energy) changes in a system, typically in processes like chemical reactions or physical changes (e.g., phase changes). Kinetic energy relates to motion, potential energy to position/configuration, and a calorimeter doesn't directly measure temperature changes (though temperature data is used to calculate thermal energy changes). So the correct option is about changes in thermal energy.

Answer:

D. changes in thermal energy
