Q3. You perform an exppriment in which a 0.032 kg sample of gaseous nitrogen at 25°C is cooled to -195.8'C. The nitrogen then undergoes a
change of state after 6368 J of energy is released, resulting in 0.032 kg
of liquid nitrogen at -19
8°C.
a) What is the significance of the temperature -195.8°C
b) Determine the latent heat of vaporization for nitrogen,
