Changes in move matter from one state to another.

a. temperature
b. pressure
c. density
d. location

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

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
