The kinetic energy per unit mass of a certain gas a 300 K is `1.3 xx 10^(5) ` J/Kg . What will be the kinetic energy per unnit mass of the gass of 600 K ?

Explanation

KE per unit mass of a gas (KE /m)` prop T`
`((KE//m)_(2))/((KE//m)_(1)) = T_(2)/T_(1)= 600/300 =2`
` (KE//m)_(2) = 2xx (KE//m)_1 = 2 xx 1.3 xx 10^(5)`
` = 2.6 xx 10^(5) ` J/kg gives the required quantity
