A gas is kept in a rigid cubical container. If a load of 10kg us put on the top of the container, does the pressure increase?

An ice cube of mass 0.1 kg at 0^@C is placed in an isolated container which is at 227^@C . The specific heat s of the container varies with temperature T according to the empirical relation s=A+BT , where A= 100 cal//kg.K and B = 2xx 10^-2 cal//kg.K^2 . If the final temperature of the container is 27^@C , determine the mass of the container. (Latent heat of fusion for water = 8xx 10^4 cal//kg , specific heat of water =10^3 cal//kg.K ).

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume ?

A large cylinderical tank of cross-sectional area 1m^(2) is filled with water . It has a small hole at a height of 1 m from the bottom. A movable piston of mass 5 kg is fitted on the top of the tank such that it can slide in the tank freely. A load of 45 kg is applied on the top of water by piston, as shown in figure. The value of v when piston is 7 m above the bottom is (g=10m//s^(2) ) (a). sqrt(120)m//s (b). 10m//s (c). 1m//s (d). 11m//s

Increase in temperature of a gas filled in a container would lead to:

Shown in the figure is a container whose top and bottom diameters are D and d respectively At the bottom of the container these is a cappillary tube of outer radius b and inner radius a. the volume flow rate in the capillary is Q. if the capillary is removed the liquid comes out with a velocity of v_(0) . The density of the liquid is given as calculate the coefficient of viscosity eta (given pia^(2)=10^(-6)m^(2) and (a^(2))/(l)=2xx10^(-6)m ]

In Fig., a container is shown to have a movable (without friction) piston on top. The container and the piston are all made of perfectly insulating material allowing no heat transfer between outside and inside the container. The container is divided into two compartments by a rigid partition made of a thermally conducting material that allows slow transfer of heat. the lower compartment of the container is filled with 2 moles of an ideal monoatomic gas at 700 K and the upper compartment is filled with 2 moles of an ideal diatomic gas at 400 K. the heat capacities per mole of an ideal monoatomic gas are C_(upsilon) = (3)/(2) R and C_(P) = (5)/(2) R , and those for an ideal diatomic gas are C_(upsilone) = (5)/(2) R and C_(P) = (7)/(2) R. Now consider the partition to be free to move without friction so that the pressure of gases in both compartments is the same. the total work done by the gases till the time they achieve equilibrium will be
