What will happen to the pressure of a gas if its temperature is reduced to -273oC?
Answer Details
When the temperature of a gas is reduced, the gas molecules lose kinetic energy and move slower. As a result, they collide less frequently and with less force with the walls of the container holding the gas, which means they exert less pressure on the walls. Therefore, if the temperature of a gas is reduced to -273°C (also known as absolute zero), the gas molecules will have no kinetic energy and will not be able to exert any pressure on the container.
So the correct answer is: "It will drop to zero."
