Question

Changes in ________ move matter from one state to another.

A.temperature
B.pressure
C.density
D.location

Answer 1

Temperature. Water is an example. When water is at room temp. its liquid. When water is at boiling temp. It is a gas. And when water is at freezing temp. Its a solid.

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

Change in state of a substance or matter is affected by changes in kinetic energy of atoms of the matter.

More is the kinetic energy within the atoms of a matter, more easily it is able to change its state.

Also, it is known that

                      $K.E \propto \frac{3}{2}kT$

This relation shows that kinetic energy is directly proportional to temperature of a substance.

Hence, we can conclude that changes in temperature move matter from one state to another.
