Kinetic Theory Of Gases Question 30
Question: The pressure of a gas is raised from $ 27{}^\circ C $ to $ 927{}^\circ C. $ The root mean square speed is
Options:
A) $ \sqrt{( 927/27 )} $ times the earlier value
B) remain the same
C) gets halved
D) get doubled
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ c _{rms}\propto \sqrt{T} $ As temperature increases from 300 K to 1200 K that is four times, so, $ c _{rms} $ will be doubled.
