If the temperature of a gas is increased from `0^(@)` to `273^(@)C`, then the ratio of change in the average kinetic energy of the gas molecule to the original isA. `1:4`B. `4:1`C. `1:1`D. `2:1`

Answer» Correct Answer - C
`KE_(1) prop T_(1) and KE_(2) prop T_(2)`
`(KE_(2))/(KE_(1))=(T_(2))/(T_(1))=(273+273)/(273)=(2xx273)/(273)=(2)/(1)`
`(KE_(2)-KE_(1))/(KE_(1))=1`
