The density of methane is maximum under which conditions?
The density of methane is maximum under which conditions?
$0^{\circ} \mathrm{C}, 2$ bar
$273^{\circ} \mathrm{C}, 1$ bar
$273^{\circ} \mathrm{C}, 2$ bar
$0^{\circ} \mathrm{C}, 3$ bar
Solution
Among the given conditions, the density of methane is maximum when temperature is $0^{\circ} \mathrm{C}$ and pressure is 3 bar. This is because density will be highest when the temperature is lowest and pressure is highest.
