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?
Jouri is going to read about the law of conservation of mass.
Ali is going to measure the mass before and after a reaction.
Seojun is going to sort the chemicals into different piles based on color.
Martha is going to mix two chemicals together and measure their temperature to see if it changes

Martha's approach would be the most directly helpful towards constructing a device that uses a chemical reaction to either release or absorb thermal energy. By mixing two chemicals together and measuring their temperature, she can directly observe whether a chemical reaction leads to an exothermic (releasing heat) or endothermic (absorbing heat) process. This information is crucial for understanding how to design the device to achieve the desired thermal energy change.
