Question

if liquid water is exposed to normal atmospheric pressure what needs to change in order to change its state of matter?

Answer 1

Increasing the temperature will cause an increase in the kinetic energy of molecules which will change its state to gas.

Answer 2

Temperature.

Step-by-step explanation:

Temperature and pressure are the two factors that affects the state of the substance. If any one of the two given factors is changed then the state of the substance will change.

If the atmosphere pressure is not changed, then temperature will be required to change the state of matter. There are certain conditions in which both the temperature and pressure is changed to see a change in the state of matter.
