Explain why
A fluid flowing out of a small hole in a vessel results in a backward thrust on the vessel.

At 10 bar pressure a 4:1 mixture of He and CH_(4) is contained in a vessel. The gas mixture leaks out through a hole present in the vessel. The mixture effusing out has an initial composition of -

The flow of blood in the dorsal blood vessel of earthworm is

A gas mixture consisting of He and CH_(4) gases in mole ratio 4:1 is present in a vessel at a pressure of 20 bar. Due to a fine hole in the vessel, the gas mixture undergoes effusion. What is the composition (or ratio) of the initial gas mixture that is effused out?

A given mass of a perrfect gas is first heated in a small and then in a large vessel, such that their volumes remain unaltered. The P-T curves are-

Explain the relation between pressure and volume of a gas confined in a closed vessel at a constant temperature,according to the kinetic theory of gases.

A cylindrical vessel contains a liquid up to a height h. A hole is made on the wall of the vessel. Water comes out through the hole and falls at a distance x from the base of the vessel. At what depth should the hole be created so that x becomes maximum?

A cubical vessel of height 1 m is full of water . What is the amount of work done in pumping water out of the vessel ? (Take g = 10 m S^(-2) )

Explain the equilibrium established in the evaporation of a liquid in a closed vessel at a particular temperature from the molecular point of view.
