1.	At 25^(@)C and 760 mm of Hg pressure of 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>676.6 mm Hg 600 mm Hg 700 mm Hg 752 mm Hg Solution :(a) According to combined gas law,`(p_(1)V_(1))/(T_(1))=(p_(2)V_(2))/T_(2)` `rArr p_(2)=((760 mm Hg)XX(600 ML)xx(283 K))/((640 mL)xx(298K))=676.6 mm Hg`
