At constant pressure, the density of a fixed mass of gas is
A
constant with temperature
B
proportional to its volume
C
inversely proportional to its temperature
D
independent of its volume
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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
