What effect does the speed of molecules have on matter? (answer as quickly as possible plz & earn 40 points)

a. it figure out the matter’s density.
b. it controls the matter’s weight.
c. it determines the mass of the matter.
d. it determines what state the matter is in.

The correct answer is D. It determines what state the matter is in.

The particular state in which matter is is dependent on the sped of the molecules hat compose matter.

Matter is composed of small particles called molecules. These molecules are in constant motion and bump into each other frequently.

In solids, the molecules that compose matter only vibrate or rotate about a fixed position.

In liquids, the molecules that compose matter can move about at low speed.

Molecules of a gas move at high speed. We can see that the particular state of matter is defined by the speed of the molecules that compose it.

D is the right option

Explanation: if the speed of the molecules are randomly fast that they are only restricted by the wall of the container, it therefore means that the matter is in gaseous state. If the speed are fast to an extent that they transfer heat to another thereby making them fast to move about, the matter is in liquid state. But when the molecules only vibrate about a fixed point, the matter is in solid state
