How is molecular motion related with temperature?


The molecular theory states that the pressure exerted by a gas in a closed vessel results from the gas molecules striking against the walls of the vessel. How will the pressure change if

  1. The temperature is doubled keeping the volume constant
  2. The volume is made half of its original value keeping the T constant 

Fill in the blanks:

The average kinetic energy of the molecules of a gas is proportional to the ………….


What volume will a gas occupy at 740 mm pressure which at 1480 nun occupies 500 cc? [Temperature being constant]


The volume of a given mass of a gas at 27°C is 100 cc. To what temperature should it be heated at the same pressure so that it will occupy a volume of 150 cc?


Calculate the following:

The temp, at which 500 cc. of a gas ‘X’ at temp. 293K occupies half it’s original volume [pressure constant].


Calculate the following:

The volume at s.t.p. occupied by a gas “Y” originally occupying 760 cc. at 300K and 70 cm. press, of Hg.


Calculate the following:

The volume at s.t.p. occupied by a gas ‘Z’ originally occupying 1.57 dm3 at 310.5K and 75 cm. press. of Hg.


Calculate the following:

The volume at s.t.p. occupied by a gas ‘Q’ originally occupying 153.7 cm3 at 287K and 750 mm. pressure [vapour pressure of gas ‘Q’ at 287K is 12 mm of Hg.]


Calculate the following:

The temperature to which a gas ‘P’ has to be heated to triple it’s volume, if the gas originally occupied 150 cm3 at 330K [pressure remaining constant].
