Calculate the specific heat of vaporization of liquid nitrogen, if the amount of heat | Q | = 804 J is released at the boiling point of nitrogen mass m = 4.0 g from the gaseous state to the liquid state
The given problems: m (mass of nitrogen that has passed into a liquid state) = 4 g (in SI m = 4 * 10 ^ -3 kg); Q (released heat) = 804 J.
To calculate the specific heat of vaporization of liquid nitrogen, we use the formula: Q = q * m, whence q = Q / m.
Let’s perform the calculation: q = 804 / (4 * 10 ^ -3) = 201 * 10 ^ 3 J / kg = 201 kJ / kg.
Answer: The specific heat of vaporization of liquid nitrogen, according to the calculation, is 201 kJ / kg.
