The temperature of an ideal gas in increased from 100 K to 400 K . If ' x ' is the r.m.s. velocity of its molecules at 100 K , then at 400 K , the r.m.s. velocity becomes
- A \(4 x\)
- B \(x / 4\)
- C \(2 x\)
- D \(3 x\)
Answer & Solution
Correct Answer
(C) \(2 x\)
Step-by-step Solution
Detailed explanation
\(v_{rms} \propto \sqrt{T}\) \(\frac{v_2}{v_1} = \sqrt{\frac{T_2}{T_1}}\)
