A cylinder containing an ideal gas is in vertical position and has a piston of mass M that is able to move up or down without friction (figure). If the temperature is increased

A

both p and V of the gas will change

B

only p will increase according to Charles' law

C

V will change but not p

D

p will change but not V

Text Solution

Verified by Experts

The correct Answer is:
A
Consider the diagram where an ideal gas is contained in a cylinder, having a piston of mass M. Friction is absent.

The pressure in side the gas will be `p=p_(a)+Mg//A`
where, `p_(a)` = atmospheric pressure
A = area of cross-section of the piston.
Mg = weight of piston
Hence, p = constant
when temperature increases
as pV = nRT `rArr` Volume (V) increases at constant pressure.

An insulated cylinder contains nitrogen gas which is sealed on the top by a heavy metal piston of mass m. piston is free to move with negligible friction, initial height of the piston is 0.3 m at temperature 27^(@)C when it is givenn some heat with the help of an electrical circuit piston slowly rises to height 0.5 m above the bottom of the cylinder. During expansion of te gas, net heat absorbed by the nitrogen gas:

A cylindrical container has insulating wall and an insulating piston which can freely move up and down without any friction. It contains a mixture of ideal gases. Originally the gas is at atmospheric pressure P_(0) and temperature (T_(0)) . A tap positioned above the container is opened and it supplies water at a constant rate of (dm)/(dt)= 0.25 kg//s . The water collects above the piston in the container and the gas compresses. The tap is kept open till the temperature of the gas is doubled. During the process the T vs (1)/(V) graph for the gas was recorded and found to be a parabola with its vertex at origin as shown in the graph. Area of piston A = 1.515 xx 10^(-3) m^(2) and atmospheric pressure = 10^(5) N//m^(2) (a) Find the ratio of V_(rms) and speed of sound in the gaseous mixture. (b) For how much time the tap was kept open?

(i) A horizontal cylinder is fitted with a smooth movable piston. The cylinder contains an ideal gas. The gas is heated slowly so that the piston gradually moves out. After moving out for some distance the piston encounters an ideal spring and compresses it while moving out. Draw P – V diagram for the entire process. (ii) One mole of an ideal gas is expanded isothermally at temperature T_(0) to double its volume from V_(0) to 2V_(0) . Draw a graph showing the variation of volume (V) of the gas versus the amount of heat (Q) added to it.
