Question

The conversion of 1 mole of water at 0°c to 1 mole of ice at 0°c releases 6.01 kj. what must be true about the heat absorbed during the melting of 1 mole of ice at 0°c to 1 mole of water at 0°c? it must be less than 6.01 kj. it must be greater than 6.01 kj. it must be 6.01 kj.

Answer 1

Answer: it must be 6.01 kJ.

Explanation:

Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to 1 mole of solid at atmospheric pressure.

$H_2O(l)\rightarrow H_2O(s)$

Given: latent heat of freezing is 6.01 kJ.

Latent heat of fusion is the amount of heat required to convert 1 mole of solid to 1 mole of liquid at atmospheric pressure. If latent heat of freezing is 6.01 kJ, latent heat of fusion will be same but the heat will be absorbed.

$H_2O(s)\rightarrow H_2O(l)$

Answer 2

It must be 6.01 kj
