A 10-lane Olympic sized swimming pool contains 2.5 x 106 kg of water. If the water is at 0ºC, how many kilojoules of energy must be removed to freeze the water in this pool? capital deltaHfus for H2O = 334 J/g

Respuesta :

Answer:

Explanation:

Given:

T = 0°C

Mass of water, M = 2.5 × 10^6 kg

Heat of fusion = 334 J/g

Heat required, Q = M × heat of fusion

= 2.5 × 10^6 kg × 1000 g/1 kg × 334 J/g × 1 kJ/1000 J

= 8.35 × 10^8 kJ.
