Endothermic, as endo means to take in and thermic means heat or energy as that is what heat is. Exothermic releases heat when it occurs and kinetic is a form of energy, energy that is doing work. Convective or convection is heat in a liquid cycling, meaning going in a cycle or heating in a circular pattern.
The compound that releases hydroxide ions in an aqueous solution would be a base.
<h3>What are bases?</h3>
Bases are substances that when ionized in water, produce hydroxide ions as the only negative ion.
Bases are as opposed to acids. The latter produces hydrogen ions as the only positive ion when ionized in water. For example, sodium hydroxide ionizes in aqueous solutions as follows:
Bases can also be defined as substances whose pH is above 7.
