Question

When the ice of a frozen lake starts to melt, the temperature of the surroundings ____.

• A. Increases
• B. Decreases
• C. remains same
• D. increases and then decreases

Answer 1

The correct option is B

Decreases

When ice of a frozen lake starts melting, it takes the latent heat required for melting from the surroundings. It results in fall in temperature of the surroundings. Or we could say that quite a large amount of heat energy required for melting the frozen lake is absorbed from the surrounding atmosphere. As a result, the temperature of the surrounding decreases and it becomes very cold.
