The temperature of nitrogen gas contained in a not rigid vessel is reduced from 100°C to 50°C? Which of the following describes the resulting behavior of nitrogen gas molecules?
I. The average kinetic energy suddenly increases, thus the pressure increases.
II. The average kinetic energy suddenly decreases, thus the pressure decreases.
III. The volume occupied by the gas molecules suddenly increases, thus the container expands.
IV. The volume occupied by the gas molecules suddenly decreases, thus the container shrinks.
