Which of the following decreases with increase in pressure ?
Correct answer: A. Melting point of ice
- A. Melting point of ice
- B. Melting point of wax
- C. Boiling point of liquids
- D. None of these
Explanation
Ice is unusual because its melting curve has a negative slope, so increasing pressure lowers its melting point. Pressure generally raises the melting point of wax and the boiling point of liquids.
