1.	A sample of a gas is found to occupy a volume of 800 cm^(3) "at" 27^(@) celsius. Calculate the temperature at which it will occupy a volume of 400 cm^(3), provided the pressure is kept constant.
Answer» SOLUTION :Here `v_(1)=800 cm^(-2) "" v_(2)= 400 cm^(3)` `T_(1)=(27+273)K=300K "" T_(2)= ?` Applying Charle.s law, `(V_(1))/(T_(1))=(V_(2))/(T_(2))` `T_(2)=(V_(2)xxT_(1))/(V_(1))=(400cm^(3)xx300K)/(800 cm^(3))=150 K` `=150-273=-123^(@)C` `:. T_(2)=-123^(@)C`
