Answer:
Under constant volume in a closed system the relationship between temperature and pressure is directly proportional.
Explanation:
As the pressure increases in the system the temperature also increases in the same order. It is explained in the Gay-Lussac's Law, also known as pressure-temperature law. If a gas is compressed i.e.
The pressure is reduced inside a container (constant volume) then the temperature inside the container is increased, it is practical demonstration of the pressure-temperature law. This mechanism is also used in refrigerators.
