  • The temperature of a gas is raised while its volume remains constant, the pressure exerted by the gas on the walls of the container increases because its molecules

    A
    lose more kinetic energy to the wall
    B
    are in contact with the wall for a shorter time
    C
    strike the wall more often with higher velocities
    D
    collide with each other with less frequency

  • As per KTG, molecules in gaseous state are under continuous motion with no intermolecular forces occurring & the speed of the molecules will keep on changing due to the molecular collections. The distribution pattern remains constant and is given by (dN)/(du) = 4 pi N (M/(2 pi R T))^(3/2) u^2 . e^((-Mu^2)/(2RT)) (symbols have usual meaning). The collisions are assumed to be perfectly elastic. In case there are more than one gas in the container then also presence of one type of gas will not affect movement of other gas than one gas. Based on this information, answer the question that follows. A closed container fitted with a movable piston always operating at fixed pressure is subjected to increase in temperature. Identify the correct option assuming a single gas to be present in the container.

    A
    Number of collisions made by any one molecule in one second will be directly proportional to root of absolute temperature.
    B
    Mean free path will increases linearly with absolute temperature
    C
    Total number of BMC in one second will increases.
    D
    Average speed of approach will remain unaffected.

    A cylindrical container of height 3L and cross sectional area A is fitted with a smooth movable piston of negligible weight. It contains an ideal diatomic gas. Under normal atmospheric pressure P_(0) the piston stays in equilibrium at a height L above the base of the container. The gas chamber is provided with a heater and a copper coil through which a cold liquid can be circulated to extract heat from the gas. Volume occupied by the heater and the liquid coil is negligible. Following set of operations are performed to take the gas through a cyclic process. (1) Heater is switched on. At the same time a tap above the cylinder is opened. Water fills slowly in the container above the piston and it is observed that the piston does not move. Water is allowed to fill the container so that the height of water column becomes L. Now the tap is closed. (2) The heater is kept on and the piston slowly moves up. Heater is switched off at the time water is at brink of overflowing. (3) Now the cold liquid is allowed to pass through the coil. The liquid extracts heat from the gas. Water is removed from the container so as to keep the position of piston fixed. Entire water is removed and the gas is brought back to atmospheric pressure. (4) The circulation of cold liquid is continued and the piston slowly falls down to the original height L above the base of the container. Circulation of liquid is stopped. Assume that the container is made of adiabatic wall and density of water is rho . Force on piston due to impact of falling water may be neglected. (a) Draw the entire cycle on a P–V graph. (b) Find the amount of heat supplied by the heater and the amount of heat extracted by the cold liquid from the gas during the complete cycle.

    A container has a tight fitting movable piston which can slide without friction. The compartment containing spring has vacuum and to the left of the piston there is diatomic gas. If vacuum is created in the right compartment also the piston touches the right wall and the spring is relaxed. Find the heat capacity of the system neglecting the heat capacities of the material of spring, container and the piston. Express your answer in terms of P_(0), V_(0) and T_(0) .

    A cylinder filled with a movable piston contains liquid water in equilibrium with water vapour at 25^@C . Which one of the following operations results in a decrease in the equilibrium vapour pressure ?

    Figure shows initial state of an ideal gas trapped in a container with conducting walls and a piston (mass m ) which can move without any friction. The container is placed on point supports and its wall are conducting. Assuming that atmospheric pressure is P_(0) and the mass of the ideal gas is negligible as compared to the mass of the piston and the mass of container. Take the cross section area of piston to be A. The piston is slowly lifted by an external agent and held in its position. Let M be the maximum mass of container so that it may "lift off" while pulling the piston upwards and P_(i) be the pressure of ideal gas in initial state. Pick the correct choice:

    Which change increases the solubility of a gas in water? (P) an increases in water temperature (Q) a decrease in gas pressure
