The kinetic energy of one mole gas at 300 K temperature , is E. at 400 K temperature kinetic energy is E' . The value of `E'//E` is

Options

A. 1.33
B. `sqrt(((4)/(3)))`
C. `(16)/(9)`
D. 2

Answer

A

Explanation

The kinetic energy of gas , `E=(3)/(2)nKTrArrEpropT`
`therefore" " (E')/(E)=(T')/(T)=(400)/(300)`
`rArr" " (E')/(E)=(4)/(3)=1.33`
