A cylinder contains accetylene gas at `27^(@)C` and `4.05M pa`. The pressure in the cylinder after half the mass of gas is used up and temperature has fallen to `12^(@)C` will be:

A cylinder contains a gas at temperature of 27^(0)C and a pressure 1MPa . If the temperature of the gas is lowered to -23^(0)C , the change in pressure is

A cylinder contains 12 litres of oxygen at 20^(@)C and 15 atm pressure. The temperature of the gas is raised to 35^(@)C and its volume increased to 17 litres. What is the final pressure of gas (in atm)?

If a cylinder at NTP contains a gas and it can withstand a temperature of 473K then pressure inside the cylinder at the time of explosion will be?

A gas cylinder contains oxygen gas at 25^@C and 15.0 atm. If the temperature of the surroundings rises to 42^@C , what would be the pressure of the gas in the cylinder ?

A cylinder contains gas at 2 xx 10^(5) Pa and 47^(@)C . The cylinder is steadily heated. Neglecting any change in its volume, find the temperature at which the cylinder will break if the walls of cylinder can bear a maximum pressure of 8 xx 10^(5) Pa

The gas in a vessel is subjected to a pressure of 20 atmosphere at a temperature 27^(@)C . The pressure of the gas in the vessel after one half of the gas is released from the vessel and the temperature of the remainder is raised by 50^(@)C is

The gas in a vessel is subjected to a pressure of 20 atmosphere at a temperature 27^(@)C . The pressure of the gas in the vessel after one half of the gas is released from the vessel and the temperature of the remainder is raised by 50^(@)C is

A gas cylinder contains 320 gm of O_(2) at 30 atm and 27^(@)C what mass (in gram) of O_(2) would escape if first the cylinder is heated to 127^(@)C and then valve is held open until the pressure the cylinder become 1 atm ( the temperature being maintained at 127^(@)C ).

A flask is filled with 13 g of an ideal gas at 27^(@)C and its temperature is raised to 52^(@)C . Find the mass of the gas that has to be released to maintain the temperature of the gas in the flask at 52^(@)C and the pressure is same as the initial pressure.
