Question
The changes in the states of matter happen upon adding the
- External energy
- Pressure
- Temperature
- All the above
Hint:
States of matter are interconvertible under applied required temperature and pressure.
The correct answer is: All the above
- When external pressure is increased boiling point would vary as we know unless A.P.=V.P. liquid doesn't boil.
- When pressure is applied gas gets converted to liquid under some specified conditions.
- When temperature increases to a point liquid start boiling.
- The changes in the states of matter happen upon adding all three.
