the volume of a fixed amount of gas is doubled, and the absolute temperature is doubled. according to the ideal gas law, how
has the pressure of the gas changed?

if the temperature is doubled, the volume increases to twice the original volume. If both the changes take place simultaneously,... The volume is directly proportional to the temperature and inversely proportional to the pressure. ... And if the temperature is doubled, the volume increases to twice the original volume.
