The initial temperature of a gas is 100^(@)C. The gas is contained in closed vessel. If the pressure on the gas is increased by 5% calculate the increase in temperature of the gas

Answer»

`1^(@)C`
`2^(@)C`
`4^(@)C`
`5^(@)C`

Solution :Volume of gas is constant
`T_(1)//T_(2) = P_(1)//P_(2)`
`(100)/((100-DeltaT)) = (P)/(1.05P)`
`105P =100P+P*Delta T`
`(5P)/(P)=Delta T = 5^(@)C`.
