(A) A closed cylinder containing high pressure gas tends to rise against gravity when the gas is allowed to escape through an orifice at the bottom
(R) The velocity of escaping gas develops an upward thrust proportional to the area of cross-section of the orifice

A

If both A and R are correct and R is the correct explanation of A

B

If both A and R are correct but R is not the correct explanation of A

C

If A is correct but R is incorrect

D

If A is incorrect but R is correct

Text Solution

Verified by Experts

The correct Answer is:
C

Assertion is correct but reason is wrong as the velocity of escaping gas is inversely proportional ot the area of cross-section of orifice

A closed vessel contains some gas at a given temperature and pressure. If the vessel is given a very high velocity, then the temperature of the gas

A rigid container contains 5 mole H_(2) gas at some pressure and temperature. The gas has been allowed to escape by simple process from the container due to which pressure of the gas becomes half of its initial pressure and temperature become (2//3)^(rd) of its initial. The mass of gas remaining is :

A container of volume 30 litre is filled with an ideal gas at one atmos pressure and 0^(@)C temperature. Keeping the temperature constant some mass of gas is allowed to escape from the container. Due to this the pressure of the gas decreases to 0.78 atmos from the previous one. If the density of the gas at N.T.P. is1.3 gm/litre, the mass of the gas remaining is -
