It is desired to increase of the volume of a gas by 20% without changing the pressure. To what temprature the gas must be heated if the initial temperature of the gas is 27^(@)C. |

Answer» <P> Solution :Let VOLUME at `27^(@)C=V cm^(3)`Final volume `=V+V=(20)/(100) =1.2 V` `therefore V_(1)-v_(1)" "T_(1)=300 K, V_(2)=1.2 V T_(2)=`? At constant `P, (V_(1))/(T_(1))=(V_(2))/(T_(2)) RARR (V)/(300) =(1.2 V)/(12)` `therefore T_(2) =360 K =(360-273)^(@)C=87^(@)C` |
