A cylinder of fixed capacity 44.8 litre. contains a monatomic gas at standard temperature and pressure. The amount of heat required to cylinder by `10^(@)C` will be.
( R= univerasl gas constant )

Options

A. R
B. 10 R
C. 20 R
D. 30 R

Explanation

( d) As we know 1 mol of any ideal gas at STP occupies a volume of 22.4 litres.
Hence number of mole of gas `mu=(44.8)/(22.4)=2`
Since the volume of cylinder is fixed, Hence `(DeltaQ)_(V)=muomegaDeltaT`
`2xx(3)/(2)Rxx10=30R" " ( :.(C_(V))_(mono)=(3)/(2)R)`
