According to Charles' law (assuming the gas is held at constant pressure), the volume of a gas is directly proportional to its temperature in Kelvin. As the temperature increases from 20°C to 40°C, the Kelvin temperature will increase from 293K to 313K. Therefore, the volume of the gas will increase slightly.
