Question

A gas balloon has volume of 106 litres when the temperature is 42 deg celsius and pressure is 740.0 mm of mercury. What will its volume be at 20 deg celsius and 780 mm of mercury pressure ​​

Answer 1

Answer:

Applying ideal gas equation considering the gas inside the balloon to be ideal,to get the new volume,

So,from ideal gas law,we get,

PVT= constant

so,we can say,

PVT=P'V'T'

Where, P=740mmofHg,P'=780mmofHg,T=(45+273)=318K,T'=(20+273)=293K,V=106L

So, V'=92.66L
