MHT CET · Physics · Kinetic Theory of Gases
The r.m.s. speed of gas molecules at 800 K will be
- A same as at 200 K
- B twice the value at 200 K
- C four times the value at 200 K
- D half the value at 200 K
Answer & Solution
Correct Answer
(B) twice the value at 200 K
Step-by-step Solution
Detailed explanation
\(v_{rms} \propto \sqrt{T}\) \(\frac{v_{rms, 800K}}{v_{rms, 200K}} = \sqrt{\frac{800 \text{ K}}{200 \text{ K}}}\)
