Lucy adds table salt to a beaker of water. After she stirs the water, a small amount of table salt remains at the bottom of the beaker. She heats the beaker for 5 minutes, and the salt on the bottom of the beaker disappears. How does heating the water cause the remaining salt to disappear?

Question

Lucy adds table salt to a beaker of water. After she stirs the water, a small amount of table salt remains at the bottom of the beaker. She heats the beaker for 5 minutes, and the salt on the bottom of the beaker disappears. How does heating the water cause the remaining salt to disappear?

a
Heating the beaker decreases the temperature of the solution. When the temperature decreases, the solubility of the table salt increases.
b
Heating the beaker increases the temperature of the solution. When the temperature increases, the solubility of the table salt increases.
c
Heating the beaker increases the temperature of the solution. When the temperature increases, the solubility of the table salt decreases.
d
Heating the beaker decreases the temperature of the solution. When the temperature decreases, the solubility of the table salt decreases.

Answer 1

b

Heating the beaker increases the temperature of the solution. When the temperature increases, the solubility of the table salt increases.
