Answers to One mark questions:Ans 1 At critical temperature, meniscus b/w liquid and vapours disappears.
Ans 2. He is incombustible , though heavier than H2.
Ans 3. Below Boyle Temperature.
Ans 4. At absolute zero (O K) temperature.

Ans 6. It is critical temperature (Tc)
Ans 7. Both decreases with increase in temperature
Ans 8. P1 = X1 x P (total)
Ans 9. At hill station the atmospheric pressure is less and so boiling point decreases.
