5.4 gm N2 gas is filled in closed container at temperature 27°C. Find the energy of the gas when rms speed of gas molecules get doubled.
(1) 4980 J (2) 9480 J (3) 5040 J (4) 9980 J
energy of a gas =
and Root mean square velocity=
when rms speed of gas molecules get doubled.
means new temperature becomes four times.
so new energy will becomes four times.
