Какое количество теплоты требуется для конденсации 100 г ртути

The heat required to condense 100 grams of mercury at its normal boiling point of 356.6 °C (674.0 °F) is approximately 635.6 kilojoules. This is determined using the heat of vaporization, which is the amount of energy required to convert a substance from a liquid to a gas at a constant temperature. The heat of vaporization for mercury is approximately 59.11 kJ/mol. To convert this to heat per gram, we divide by the molar mass of mercury (200.59 g/mol) to get 0.295 kJ/g. Multiplying this by 100 g gives 29.5 kJ or 635.6 kJ/100g.
