# What type of process occurred when salt A dissolved in water?

## Two grams of salt A were added to 50 mL of water, and the initial and final temperatures were recorded on the left side of Table 8 below. In a separate experiment, 2 g of salt B were added to 50 mL of water, and the initial and final temperatures were recorded on the right side of Table 8 below. $\boldsymbol{\text{Table 8: Temperature Data for Salt A and Salt B}}$ bbul(color(white)(mmmm)"Salt A"color(white)(mmmmmmmmm)"Salt B"color(white)(mmmmm) $\text{Initial Temperature 20 ˚C"color(white)(m)"InitialTemperature 20 ˚C}$ $\text{Final Temperature"color(white)(ll) "35 °C"color(white)(m)"Final Temperature"color(white)(l) "10 °C}$ Answers: Heat Endothermic Enthalpy Exothermic

A process is Endothermic when it requires energy input. A process is Exothermic when it releases energy.

#### Explanation:

If the water solution is cooler after the salt addition, it is an endothermic process.
If the solution is warmer after the salt addition, it is an exothermic process.
