1.	At 25^(@)C and 760 mm of Hg pressure a gas occupies 600 mL volume. What will be its pressure at a height where temperature is 10^(@)C and volume of the gas is 640 mL.
Answer» <P> Solution :Value of gases as follows Initial temperature `(T_(1))=25^(@)C+273=298 K` At High temperature `(T_(2))=10^(@)C+273=283 K` Initial VOLUME `(V_(1))=600 ml` High volume `(V_(2))=640 ml` Initial Pressure `(p_(1))=760` mm of HG. High Pressure `(p_(2))=(?)` `(p_(1)V_(1))/(T_(1))=(p_(2)V_(2))/(T_(2)) ""`.....(Combined GAS law) `p_(2)=(("760 mm Hg")(600 mL))/((298 K))XX((283 K))/((640 mL))` = 676.634 mm Hg `~~ 676.3` mm Hg.
