As per kinetic theory of gases which of the following statements is / are true?
a) Temperature of a gas is a measure of average kinetic energy of a molecule
b) Temperature of a gas depends on the nature of the gas
c) Heavier molecule has lower average speed
d) Lighter molecule has lower average speed
- A a & b are true
- B b & c are true
- C a & c are true
- D b & d are true
Answer & Solution
Correct Answer
(C) a & c are true
Step-by-step Solution
Detailed explanation
The formula of drift velocity or average velocity is, vd=eEτm, so we can say that drift velocity is inversely proportional to the mass of the molecule so heavier molecules having lesser speed compared to the lightest molecules. The formula of average kinetic energy,…
