A perfect gas of volume 10 liter is compressed isothermally to a volume of 1 liter. The rms sped of the molecules will

A
decrease 5 time
Correct answer
B
remain unchanged
C
increase 5 times
D
increase 10 times

Solution

Process is isothermal, hence temperature as well as rms speed remain same.

Hence, the correct answer is option: 'B'.
