_______________ increases with increase in pressure?
Correct answer: C. Both A. and B
- A. The melting point of wax
- B. The boiling point of a liquid
- C. Both A. and B
- D. Neither A. nor B
Explanation
Increasing pressure raises a liquid’s boiling point because a higher temperature is needed for its vapour pressure to match the pressure. Waxes generally expand on melting, so pressure also raises their melting point, making both statements applicable.
