Question

The kinetic energy per cubic metre of a perfect gas at N.T.P. is (Take atmospheric pressure = 1 x 105 N/m2)

1) 1.5 x 105 J/m3        2)  2 x 105 J/m3          

3)  0.75 x 105 J/m3     4)  2.5 x 105 J/m3


​

Answer 1

Answer:

3) 0.75 ×105 J/m3 will be correct answer

please mark me as brainlist

Answer 2

Answer: A

Explanation:

K.E. = 3/2 PV

K.E. / V = 3/2 x 1 x 10^5

K.E. / V = 1.5 x 10^5
