A balloon contains 14.0 L of air at 760 torr. What will be the volume of the balloon when it is taken to a depth of 10 ft. in a swimming pool? Assume that the temperature of the air and water are equal. (density : Hg=13.6g/mL.)
A partially inflated balloon contains 500 m^3 of helium at 27^@ C and 1 atm pressure. What is the volume of the helium at an altitude of 18000 ft , where the pressure is 0.5 atm and the temperature is -3^@ C ?
On a ship sailing in pacific ocean, where temperature is 22^(@)C , a balloon is filled with 2L air. What will be the voume of balloon when the ship reaches Indian ocean, where temperature is 27^(@)C ? The atmospheric pressure is same over pacific ocean and Indian ocean.
A high-altitude balloon is filled with 1.41xx10^(4)L of hydrogen at a temperature of 21^(@)C and a pressure of 745 torr. What is the volume of the balloon at a height of 20 km, where the temperature is -48^(@)C and the pressure is 63.1 torr?
What would be the height of the atmosphere if the air density (a) were uniform and (b) decreased linearly to zero with height? Assume that at sea level the air pressure is 1.0 atm and the air density is 1.3 kg/ m^(3)
A balloon filled with hydrogen has a volume of 1000 litres and has mass of 1kg. What would be the volume of the block of very light material which it can just lift? One litre of the material has a mass 91.3g and density of air is 1.3 g" ""litre"^(-1).
Two vessel of volumes 5 and 3 litres contain air at pressure of 3 and 7 atmospheres, respectively . What will be the resultant pressure when they are conncected through a small - bore tube ? Assume that the temperature remains constant throughout .
A spherial balloon contains air at temperature T_(0) and pressure P_(0) . The balloon material is such that the instantaneous pressure inside is proportional to the square of the diameter. When the volume of the balloon doubles as a result of heat transfer, the expansion follows the law
Calculate the volume of the balloon filled with hydrogen gas, which will be sufficient to lift a load of 25 kg in air. Given that the densities of air and hydrogen are 0.00129g//c c and 0.00009 g//c c respectively.
