Ann dissolves four tablespoons of salt in a bowl of water. She notices that the water has become salty. Ann then keeps the bowl out in the sun for along time. The water in the bowl evaporates, leaving crystals of salt behind in the bowl.
What kinds of change(s) have happened?
1)The salt dissolving is a physical change and the evaporation of water is a chemical change.
2)Both the salt dissolving and the evaporation of water are physical changes.
3)The salt dissolving is a chemical change, and the evaporation of water is a physical change.
4)Both the salt dissolving and the evaporation of water are chemical changes

2)Both the salt dissolving and the evaporation of water are physical changes.

Explanation:

The two kinds of changes that has occurred are both physical changes.

Dissolution of a solute such as salt in water and evaporation of water from a solution are physical changes.

A physical change is one in which the physical property of matter is altered. Particularly the state and the form.

In many of these cases, the change is easily reversible.

Since this change is reversible in that we were able to collect the salt back, this is a physical change.

the answer is the first option

explanation:

just googled it m8. not that hard

lol
