Question

KE per unit volume is E. The pressure exerted by the gas is given by
A. `E/3`
B. `(2E)/2`
C. `(3E)/2`
D. `E/2`

Answer 1

Correct Answer - B
The pressure exerted by the gas,
`" " p=1/3pv^(2)=1/3m/Vv^(2)=2/3(1/2mv^(2))`
`"("therefore1/2mv^(2)=E/V=` energy per unit volume, i.e.V=1)
`rArr" "p=2/3E`
