We are asked which of the following statements is TRUE.

Analyze each statement:

A. If the heat of the solution is negative for a solid in a liquid, then more solid will dissolve at higher temperatures.

• If the heat of the solution is negative this means that it is exothermic.
• When a reaction is exothermic, the system or the reaction is releasing heat to the surroundings.
