The answer is; in the summer

Insects such as blowflies increase their population in the summers when the temperatures are warm.

Have your ideas about what happens to molecules in the liquid, solid, and gas phase changed? If so, how? What evidence supports
Westkost [7]

Various states of matter have molecules moving at different velocities.

<h3>Molecules in matter</h3>

Matter is composed of molecules. These molecules that compose matter are in constant random motion. The kinetic energy and velocity of the molecules depends on the state of matter.

Molecules of a gas are fastest followed by molecules in a liquid. Molecules in a solid do not move at all hence solids have a definite shape.
