100cm3 of a gas at 27°c is cooled to 20°c at constant pressure .calculate volume of a gas at 20°c

Expert Answer:

At constant pressure, volume is directly proportional to temperature.
straight V subscript 1 over straight V subscript 2 equals straight T subscript 1 over straight T subscript 2
100 over straight V subscript 2 equals fraction numerator 273 plus 27 over denominator 273 plus 20 end fraction
100 over straight V subscript 2 equals 300 over 293
straight V subscript 2 equals 97.6 space cm cubed
