A vessel of volume V is evacuated by means of a piston air pump. One piston stroke captures the volume `v_0`. The pressure in the vessel is to be reduced to `(1/n)` of its original pressure ,`P_0`. If the process is assumed to be isothermal and air is considered an ideal gas, the number of strokes needed in the process is

A

`[(ℓ n n)/(ℓn(1- v_0/V))]`

B

`[(ℓ n n)/(ℓn(1+ v_0/V))]`

C

`[(ℓn(1- v_0/V))/(ℓn)]`

D

None of these

A vessel of volume V is evacuated by means of a piston air pump. One piston stroke captures the volume Delta V . How many strokes are needed to reduce the pressure in the vessel eta times ? The process is assumed to be isothermal, and the gas ideal.

A vessel of volume V is evacuated by means of a piston air pump Upon cach double stroke a piston pump sucks in a volume V of air and expels it. The process is assumed to be isothermal, and the gas is ideal. When this pump is used to evacuate the air from a vessel with a volume V, it performs n double strokes. The initial pressure inside the vessel is p_0 which is equal to the atmospheric pressure. (a) Calculate the final pressure inside the vessel.

The pressure p and volume V of an ideal gas both increase in a process.

In a isothermal process on an ideal gas, the pressure increases by 0.5% . The volume decreases by about.

A gas is enclosed in a vessel of volume V at a pressure P . It is being pumped out of the vessel by mean of a piston-pump with a stroke volume. v . What is the final pressure in the vessel after 'n' strokes of the pump ? Assume temperature reamains constant.

The pressure P and volume V of an ideal gas both decreases in a process.

Find the pressure of air in a vessel being evacuated as a function of evacuation time t . The vessel volume is V , the initial pressure is p_0 . The process is assumed to be isothermal, and the evacuation rate equal to C and independent of pressure. The evatuation rate is the gas volume being evacuated per unit time, with that volume being measured under the gas pressure attained by that moment.

A vessel contaning 10 litre of air under a pressure of 1MPa is connected to a 4 litre empty vessel. The final air pressure in the vessel assuming that the process is isothermal.

The pressure ( P ) and volume ( V ) of an ideal gas both increase in a process:
