Thermic is referring to heat. So, an endothermic reaction would be absorbing heat while an exothermic reaction would be exerting heat. All of the answers except D exert heat. Mixing the Epsom salt into water would be absorbing heat.

The answer is D.) mixing Epsom salt in water

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
