What happens to the volume of a gas when the temperature is increased?

a
The volume is decreased
b
The volume stays the same
c
The volume is increased

c) The volume is increased

c. The volume is increased

c. The volume is increased.

When the temperature of a gas is increased, the volume of the gas also increases. This relationship is known as Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature.

To explain how this relationship works, we can use the ideal gas law equation: PV = nRT. In this equation, P represents the pressure, V represents the volume, n represents the number of moles of gas, R is the ideal gas constant, and T represents the absolute temperature.

If we keep the pressure constant and increase the temperature, according to Charles's Law, the volume of the gas will increase. This is because the increase in temperature causes the gas molecules to move with greater kinetic energy, resulting in more collisions with each other and with the container walls. This increased collision frequency leads to an expansion of the gas, resulting in an increase in volume.

Therefore, when the temperature of a gas is increased, the volume of the gas also increases.
