NEET · Physics · STD 11 - 12 . kinetic theory of gases
When the temperature of a gas is raised from \(30^o C\) to \(90^o C\) , the percentage increase in the \(r.m.s.\) velocity of the molecules will be
- A \(30\)
- B \(60\)
- C \(15\)
- D \(10\)
Answer & Solution
Correct Answer
(D) \(10\)
Step-by-step Solution
Detailed explanation
\(T_1=273+30=303 K \quad T_2=273+90=373 K\) \(V_{r m s} \propto \sqrt{T}\)
