What happens as you decrease the temperature of a solution?
the number of solute particles increases.
the number of solute particles decreases.
the rate of dissolution increases.
the rate of dissolution decreases.
the temperature has no effect on the rate of dissolution.

Option (a) is the correct answer.

Explanation:

If the temperature of a solution is increased then there will be more collision between the particles which results in more energy.

Therefore, there will be less number of particles in the solution.

When we decrease the temperature of a solution then the energy of solution molecules will decrease. As a result, the number of solute particles will increase in the solution.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
