  1. Thermometer
  2. Barometer
  3. Calorimeter ✓
  4. Spectrometer

Explanation

A calorimeter measures heat of reaction. It traps heat released or absorbed. Scientists use it to study energy changes in reactions.

Thermometers measure temperature only. Barometers measure air pressure. Spectrometers analyze light, not heat.

Remember: Calor means heat in Latin. Calorimeters measure thermal energy changes.
