Answer all questions in this section.
0 1 Figure 1 shows a perfectly insulated cylinder containing 0.050 kg of liquid nitrogen at
a temperature of 70 K.
A heater transfers energy at a constant rate of 12 W to the nitrogen.
A piston maintains the pressure at 1.0 × 105 Pa during the heating process.

0 1 . 1 The nitrogen is heated from 70 K and is completely turned into a gas after 890 s. Box
Calculate the specific heat capacity of liquid nitrogen.
Give an appropriate unit for your answer.
Specific latent heat of vaporisation of nitrogen = 2.0 × 105 J kg−1
Boiling point of nitrogen = 77 K

0 1 . 2 The work done by the nitrogen in the cylinder when expanding due to a change of Box
state is X.
The energy required to change the state of the nitrogen from a liquid to a gas is Y.
Deduce which is greater, X or Y.
Density of liquid nitrogen at its boiling temperature = 810 kg m−3
Density of nitrogen gas at its boiling temperature = 3.8 kg m−3
