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
Correct Answer: C
Explanation
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
