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
- The temperature is doubled keeping the volume constant
- The volume is made half of its original value keeping the T constant
State the following:
STP conditions
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].
