For the same rise in temperature of one mole of gas at constant volume , heat required for a non - linear tratomic gas is K times that required for monoatomic gas . The value of K is

Options

A. 1
B. 0.5
C. 2
D. 2.5

Answer

C

Explanation

For a non -liner triatomic gas , `C_(V)'=3R`
and for monoatomic gas `C_(V)'=(3)/(2)R`
`therefore" " (Q)/(Q')=(C_(v))/C_(v')=K=(3R)/((3)/(2)R)=2`
