Question

Сколько теплоьы выделиьбся при замерщании 2 кг воды при 0° С.

Answer 1

Q = λm = 335000*2 = 670 кДж

Answer 2

Calculating Heat Release from Freezing 2 kg of Water at 0°C

When 2 kg of water freezes at 0°C, the heat released can be calculated using the formula:

Q = m * L

Where: - Q is the heat released - m is the mass of the substance (in this case, 2 kg) - L is the specific latent heat of fusion for water, which is 334,000 J/kg

Using this formula, the heat released can be calculated as follows:

Q = 2 kg * 334,000 J/kg Q = 668,000 J

Therefore, when 2 kg of water freezes at 0°C, approximately 668,000 joules of heat are released.
