A volume of a fixed gas is doubled and the temperature is doubled. What happens to the pressure of the gas?
Montano1993 [528]
We first assume that this gas is an ideal gas where it follows the ideal gas equation. The said equation is expressed as: PV = nRT. From this equation, we can predict the changes in the pressure, volume and temperature. If the volume and the temperature of this gas is doubled, then the pressure still stays the same.
