Two containers A and B of equal volume V_(0)//2 each are connected by a narrow tube which can be closed by a value. The containers are fitted with pistons which can be moved to change the volumes. Initially the value is open and the containers contain an ideal gas (C_(p)//C_(v)=gamma) at atmospheric pressure P_(0) and atmospheric temperature 2T_(0) . The walls of the containers A are highly conducting and of B are non-conducting. The value is now closed and the pistons are slowly pulled out to increase the volumes of the containers to double the original value. (a) Calculate the temperature and pressure in the two containers. (b) The value is now opened for sufficient time so that the gases acquire a common temperature and pressure. Find the new values of the temperature and the pressure.

Assertion : A solid and hollow sphere of same diameter and same material when heated through the same temperature will expand by the same amount. Reason : The change in volume us independent of the original mass but depends on original volume.

Consider the following statements and arrange in the order of true/false as given in the codes. S_(1) : Change in state function between two states is a definite quantity and does not depend on path. S_(2) : Intensive properties can't be algebraically added or subtracted. S_(3) : Ration of two extensive properties always result into a parameter that depends on amount of substance. S_(4) : Molar heat capacity is a path function. The correct order of True//false of the above statement is :

W denotes the corresponding work done on the system. The equations and plots in the table have standard notations as used in thermodynamic process. Here is the ratio of heat capacities at constant pressure and constant volume. The number of moles in the gas in n. What one of the following options correctly represents a thermodynamic process that is used as a correction in the determination of the speed of sound in an ideas gas?

The change in the magnitude of the volume of an ideal gas when a small additional pressure DeltaP is applied at a constant temperature, is the same as the change when the temperature is reduced by a small quantity DeltaT at constant pressure. The initial temperature and pressure of the gas were 300 K and 2 atm. respectively. If |DeltaT|=C|DeltaP| then value of C in (K/atm) is __________.
