Question
A sample of 48.6 g of water was placed in a calorimeter, and the temperature of that water sample was measured to be 24.1 °C. When 1.57 g of solid NaOH was dissolved in that water, the temperature of the solution increased to 35.6 °C.

Which one of the following statements is true?

- a. The temperature of the solution increases from 24.1 °C to 35.6 °C; therefore, the dissolution process is exothermic. ✔
- b. The temperature of the solution increases from 24.1 °C to 35.6 °C; therefore, the dissolution process is endothermic.
- c. The dissolution process is endothermic because there are 48.6 g of water and only 1.57 g of NaOH.
- d. The dissolution process is exothermic because there are 48.6 g of water and only 1.57 g of NaOH.
