An ideal gas is enclosed in a cyclinder ...

An ideal gas is enclosed in a cyclinder with a movable piston on top. The piston has mass of 8000g and an area of `5.00cm^2` and is free to slide up and down, keeping the pressure of the gas constant. How much work is done as the temperature of `0.200mol` of the gas is raised from `200^@C` to `300^@C`?

Text Solution

Verified by Experts

The correct Answer is:
A
`pV=nRT`
`:.` `pDeltaV=nRDeltaT`
Work done under constant pressure is
`W=pDeltaV=nRDeltaT`
`=(0.2)(8.31)(100)=166.2J`

(i) An adiabatic cylinder contains an ideal gas. It is fitted with a freely movable insulating piston. In one experiment the piston is pulled out very fast to double the volume of the gas. In another experiment starting from same initial state, the piston is pulled out very slowly to double the volume of the gas. At the end of which experiment the final pressure of the gas will be higher? (ii) An ideal gas is contained in a cylinder fitted with a movable piston. In an experiment ‘A’ the gas is allowed to perform a work W (gt 0) on the surrounding during an isobaric process and thereafter the pressure of the gas is reduced isochorically to half the initial value. At the end of the experiment the temperature of the gas is T_(A) . In a different experiment ‘B’ the pressure of the gas is reduced to half in an isochoric process and then the gas performs a work W on the surrounding during an isobaric process. At the end of the experiment the gas temperature is T_(B) . Which is higher, T_(A) or T_(B) ?

A diatomic gas is enclosed in a vessel fitted with massless movable piston. Area of cross section of vessel is 1m^2 . Initial height of the piston is 1m (see the figure). The initial temperature of the gas is 300K. The temperature of the gas is increased to 400K, keeping pressure constant, calculate the new height of the piston. The piston is brought to its initial position with no heat exchange. Calculate the final temperature of the gas. You can leave answer in fraction.

Suppose there are N molecules each of mass m, of an ideal gas in a container. The x component of velocity of a molecule is denoted by u_(x) . The gas is enclosed using a horizontal piston of area A as shown. If the piston is moved so as to reduce the volume of gas by half, keeping the temperature of gas constant , we know from the gas law that the pressure will be doubled. On microscopic level the increase in pressure on the piston is because

An ideal gas is enclosed in a cylinder having cross sectional area A. The piston of mass M has its lower face inclined at theta to the horizontal. The lower face of the piston also has a hemispherical bulge of radius r. The atmospheric pressure is P_(0) . (a) Find pressure of the gas. (b) The piston is slowly pulled up by a distance x. During the process the piston is always maintained in equilibrium by adding heat to the gas. [It means if the piston is left at any stage it will stay there in equilibrium]. Find change in temperature of the gas. Number of mole of the gas in the cylinder is one.
