If pressure of a gas is quadrupled and the temperature in degrees kelvin is doubled, the density of the will become …………….. Times

Text Solution

Verified by Experts

The correct Answer is:
2
`d=(PM)/(RT)`
`:.(d_(1))/(d_(2))=(P_(1))/(T_(1))xx(T_(2))/(P_(2))=(P_(1))/(P_(2))xx(T_(2))/(T_(1))=(1)/(4)xx(2)/(1)=(1)/(2)`
`:. d_(2)=2d_(1)`
