At constant pressure, the density of a fixed mass of gas is
constant with temperature
proportional to its volume
inversely proportional to its temperature
independent of its volume
คำอธิบาย
Density = mass/ volume
At constant pressure, volume is directly proportional to Temperature
Density is inversely proportional to the volume at constant mass
At constant pressure, volume = constant x temperature
hence, density = mass/ (constant x temperature)
which shows density is inversely proportional to temperature
