Water stands at level A in the arrangement shown in the figure. What will happen if a jet of air is gently blown into the horizontal tube in the direction shown in the figure?

A tank is filled upto a height 2 H with a liquid and is placed on a platform of height H from the ground. The distance y from the ground where a small hole is made in the tank, to get the maximum horizontal range R is

An inverted vessel (bell) lying at the bottom of a lake 47.6 m deep has 50 cm³ of air trapped in it. The bell is brought to the surface of the lake the volume of the trapped air now be (atmospheric pressure = 70 cm of mercury, density of mercury = 13.6 gm/cm³ and g =980 cm/s²)

To what temperature should be the hydrogen at 327^oC be cooled at constant pressure so that the root mean square velocity of its molecules becomes half of its previous value

Two gases A and B having the same temperature T, same pressure P and same volume V are mixed. If the mixture is at the same temperature T and occupies a volume V. the pressure of the mixture is

A container has N molecules at absolute temperature T. If the number of molecules is doubled but kinetic energy in the box remains the same as before, the absolute temperature of the gas is

The fig. shows the volume V versus temperature T graphs for a certain mass of a perfect gas at two constant pressures of P₁ and P₂. what inference can you draw from the graphs?

The air density at Mount Everest is less than that at the sea level. It is found by mountaineers that for one trip lasting a few hours, the extra oxygen needed by them corresponds to 30,000 cc at sea level (pressure 1 atmosphere, temperature 27^oC). Assuming that the temperature around Mount Everest is – 73^oC and that the oxygen cylinder has capacity of 5.2 liters, the pressure at which oxygen be filled (at site) in the cylinder is

A fixed amount of nitrogen gas (1 mole) is taken and is subjected to pressure and temperature variation. The experiment is performed at high pressures as well as high temperatures. The results obtained are shown in the Fig. The correct variation of PV/RT will be exhibited by with P

The change in volume V with respect to an increase in pressure P is shown in the adjoining diagram. For a fixed amount of a non ideal gas at a temperature T of the gas, the temperature T of the gas must be p
