One mole of an ideal gas requires 207 J heat to raise the temperature by 10K When heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by 5K, then the heat required isA. 62 JB. 124 JC. 12.4 JD. 6.2 J

Answer» Correct Answer - 1
`207=C_(p)xx10`
`DeltaQ=C_(v)xx5`
`C_(v)=C_(p)-R =12.4`
`DeltaQ=nQ DeltaT=62 J`
`C_(p)=207`
`C_(v)=20.7-8.3=12.4`
`DeltaQ=1xx12.4 xx5`
