Explanation

Explanation

• Latent heat of fusion is the heat required to change ice into water at 0°C.
• For ice, it is approximately 80 cal/g.
• In SI units, it is about 334 J/g.
• During melting, the temperature remains constant.
• The heat is used to change the state of matter, not raise its temperature.

Explanation

• Boyle’s Law states that pressure and volume are inversely proportional.
• It applies when temperature remains constant.
• Formula: P∝ 1/v
• Therefore, PV = constant
• If volume decreases, pressure increases, and vice versa.
