  • A Constant with temperature
  • B Proportional to its volume
  • C Inversely proportional to its temperature
  • D Independent of its volume
Correct Answer: Option 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
