Question

How much water remains unfrozen after 62.2 kJ is transferred as heat from 364 g of liquid water initially at its freezing point? The latent heat of fusion is 333 kJ/kg.

Answer 1

177.213 grams

Step-by-step explanation:

Given:

Total amount of water = 364 grams

Latent heat of fusion = 333 kJ/kg

Heat transferred = 62.2 kJ

The amount of water frozen = 62.2/333 = 0.186786 kg = 186.786 grams

Hence, the amount of water remained unfrozen = Total water - Amount of water frozen

the amount of water remained unfrozen = 364 grams - 186.786 grams = 177.213 grams
