A cylinderical vessel made of thermally isulating material is divided into two equal parts by an insulating (moveable & smooth) piston. Both parts hae same ideal gas `((V_(p))/(C_(v))=(3)/(2))`. The gas in left part is supplied heat such that volume of right part becomes one fourth of initial value.
`(PVT,PVT)`
(1) In right part, the pressure becomes eight times of its inital value
(2) In right part, the temperature becomes two times
(3) In right part, work done by gas =3PV
(4) In right part, work done by gas=-2PV

A thermally insulated container is divided into two parts by a screen. In one part the pressure and temperature are P and T for an ideal gas filled. In the second part it is vacuum. If now a small hole is created in the screen, then the temperature of the gas will

A vertical cylinder closed at both ends is divided into two parts by a frictionless piston, each part containing one mole of air. At 300K the volume of the upper part is 4 times of the lower part. At what temperature will the volume of the upper part be three times that of the lower part?

A cylinder closed at both ends is separated into two equal parts (45 cm each) by a piston impermeable to heat. Both the parts contain the same masses of gas at a temperature of 300 K and a pressure of 1 atm. If now the gas in one of parts is heated such that the piston shifts by 5 cm, then the temperature and the pressure of the gas in this part after heating is
