Explanation:
According to Charle's law, at constant pressure the volume of an ideal gas is directly proportional to the temperature.
That is,
Hence, it is given that is 3.50 liters, is 20 degree celsius, and is 100 degree celsius.
Therefore, calculate as follows.
= 17.5 liter
Thus, we can conclude that volume of gas required at 100 degree celsius is 17.5 liter.
Because they have a full outer shell and they are both noble gases
