Question

In a heating curve of ice and water, which part represents the latent heat of fusion?

विकल्प

• Rising line below 0°C

• Flat line at 0°C

• Rising line from 0°C to 100°C

• Flat line at 100°C

Answer 1

Flat line at 0°C

Explanation:

During melting, temperature stays at 0°C while heat is used to convert ice into water; this flat region corresponds to latent heat of fusion.
