If it were possible for a gas in a container to reach the temperature 0K, its pressure would be zero. Would the molecules not collide with the walls? Would they not transfer momentum to the walls?

On colliding with the walls in a closed container , the ideal gas molecules.

The 2.0 Omega resistor show in figure is dipped into a calorimeter containing water. The heat capacity of the calorimeter together with water is 2000 J K^(-1) . (a) If the circuit is active for 15 minutes, what would be the rise in the temperature of the water? (b) Suppose the 6.0 Omega resistor gets burnt. What would be the rise in the temperature of the water in the next 15 minutes? (Figure)

The pressure exerted on the walls of gas container is due to_________imparted by the gas molecule on the walls.

An ideal gas is pumped into a rigid container having diathermic walls so that the temperature remains constant. In a certain time interval, the pressure in the container is doubled. Is the internal energy of the contains of the container also doubled in the interval?

Fig shows a cylindrical tube of volume V with adiabatic walls containing an ideal gas. The internal energy of this ideal gas is given by 1.5nRT. The tube is divided into two equal parts by a fixed diathermic wall. Initially, the pressure and the temperature are p_(1), T_(1) on the left and p_(2), T_(2) on the right. the system is left for sufficient time so that the temperature becomes equal on the two sides. (a) how much work has been done by the gas on the left part ? (b) find the final pressures on the two sides. (c ) find the final equilibrium temperature. (d) how much heat has flown from the gas on the right to the gas on the left ?

Two vessels A and B of equal volume (V_0) are connected by a narrow tube which can be closed by a value. The vessels are fitted with piston which can be moved to change the volumes. Initially, the valve is open and the vessels contain an ideal gas (C_p / C_v = gamma ) at atomspheric pressures (P_0) and atmoshpeheric temperature (T_0) . The walls of the vessels A are diathermic and those of B are adiabatic. The value is now closed and the pistons are slowly pulled out to increase the volumes of the of the vessels to dobuled the original value.(a) Find the temperatures and pressures in the two vessels. (b) The value is now opened for sufficeint time so that the gases acquire a common tempertures and pressures . Find the new values of the temperatuere and the pressures.

Figure shows water in a container having 2.0-mm thick walls made of a material of thermal conductivity 0.50Wm^(-1)C^(-1) . The container is kept in a melting-ice bath at 0^(@)C . The total surface area in contact with water is 0.05m^(2) . A wheel is clamped inside the water and is coupled to a block of mass M as shown in the figure. As the goes down, the wheel rotates. It is found that after some time a steady state is reached in which the block goes down with a constant speed of 10cms^(-1) and the temperature of the water remains constant at 1.0^(@)C .Find the mass M of the block. Assume that the heat flow out of the water only through the walls in contact. Take g=10ms^(-2) .

A monatomic ideal gas is contained in a rigid container of volume V with walls of total inner surface area A, thickness x and thermal conductivity K. The gas is at an initial temperature t_(0) and pressure P_(0) . Find the pressure of the gas as a function of time if the temperature of the surrounding air is T_(s) . All temperature are in absolute scale.
