When water is in its gaseous form, the molecules are spread far apart and moving very quickly. In the liquid form, molecules are spread evenly and move at an average speed. In its solid form, the molecules are very close together and move very slowly.
At higher temperatures the speed of molecule is higher.
An indirect measurement of the speed of molecules is made with a thermometer.
When water goes from a gas to a liquid, or a liquid to a solid, the water molecules have lower kinetic energy, and therefore they lose speed.
Their speed - Kinetic Energy - increases as the solid melts.
The water molecules would speed up, but not to the point of boiling.
Slow down and the temperature drops.
The speed of the molecules speeds up when the gas is heated.
A meaningless arrangement of words.
At higher temperatures the speed of molecule is higher.
When a gas is heated it's molecules begin to move faster and farther apart, juat as all other states of matter will when heated.
the speed of the molecules decreases.
An indirect measurement of the speed of molecules is made with a thermometer.
The speed of light is the fastest speed we know about.

A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
Velocity is a vectorial quantity, speed with a direction.
