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
Correct answer is C
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

Correct answer is C
100oC .... 5.5
θoC .... 5.3
0oC .... 5.0
θ−0100−0 = 5.5−5.05.5−5.0
θ = 40oC
800kgm3
1200kgm3

2000kgm3
Correct answer is A
R.d = 0.40.5 = 0.8
0.8 = Density of oilDensity of water
0.8 = Density of oil1000
Density of oil = 800kgm3
