Question
Four students were asked to construct a device that uses a chemical reaction to either release or absorb thermal energy. Which approach would be the most directly helpful towards that goal? A. Seojun is going to sort the chemicals into different piles based on color. B. Ali is going to measure the mass before and after a reaction. C. Martha is going to mix two chemicals together and measure their temperature to see if it changes. D. Jouri is going to read about the law of conservation of mass.

The most directly helpful approach towards constructing a device that uses a chemical reaction to either release or absorb thermal energy is **C. Martha is going to mix two chemicals together and measure their temperature to see if it changes.**
This approach directly investigates the thermal energy aspect of a chemical reaction by observing temperature changes, which indicates whether the reaction is exothermic (releases heat) or endothermic (absorbs heat). The other options either involve sorting or measuring mass, which are less relevant to directly assessing thermal changes during a chemical reaction.
