Answer #1

Formula:- At constant pressure, according to Charle's law,

...(1)

Given:-

  

from eq(1) we get

Therefore, at 82 °C the volume of balloon will be 3060.13 ml.

Note:-

Charle's law:-

at constant pressure, volume of given mass of gas is directly proportional to absolute temperature.

ie. ie

Therefore,
