## Q.

Asked by Arushi Juyal 16th December 2017 8:20 AM

## At what temperature in degree centigrade will the volume of gas at 0 degree Celsius double itself.pressure remaining constant

Asked by Sheikanees02 1st November 2018 8:25 PM

## A gas 'X' is collected over warer at 17°C and 750mm pressure. If the volume of the gas collected is 50cc., calculate the volume of the dry gas at s.t.p.[at 17°C the vapour pressure is 14mm].

## Please solve these numerical by boyle's and charle's law 1.A gas occupies 3 litres at 0°C. What volume will it occupy at -20°C, pressure remains constant? (Ans.2.78 litres) 2.870 cc of moist hydrogen measured at 9°C and 659 mm pressure. Find the volume of dry hydrogen at N.T.P. The vapour pressure of water at 9°C is 9 mm.(ans.715.9 cc) 3. A sample of carbon dioxide occupies 30 cm3 at 15°C and 740 mm pressure. Find its volume at S.T.P.(ans. 27.7 cc) 4. A gas occupies a volume of 1000 cc at 0°C and 760 mm pressure.  Find the volume of gas if temperature of the gas is increased by one fifth and its pressure is increased one and half times.(ans.800 cc) 5. A fixed volume of a gas occupies 380 cc at 27°C and 70 cm of mercury. What is its volume at S.T.P.(ans.318.5 cc) 6. The pressure of a gas at S.T.P. is doulbed and the temperature is raised to 273°C. What is the final volume of the gas.  7. One litre of a gas weighs 1.33g at 750 mm of mercury and 77°C. Calculate the weight of 500 ml of the gas at 37°C and 640 mm hg.(ans.0.640 g)  8. At 0°C and 760mm hg pressure  , a gas occupies a volume of 100 cm3. The kelvin temperature of the gas increased by one-fifth while the pressure is increased one and half times. Calculate the final volume of the gas. (Ans. 80 cc)

## A gas is contained in a vessel of capacity x liters at a pressure of 20 ATM. This container is connected to another empty container of same capacity .Find the new pressure of gas assuming the temperature to be constant

Asked by Rajrashi2016 26th April 2019 6:59 PM

## The volume occupied by a certain gas was found 5.6 dm3  when the pressure was 2 atmosphere. If the  pressure is increased by 15%, find the new volume of the gas.
