Do you make a balloon lighter when you blow it up?
If you blow it up with your mouth you make it heavier. You breathe out air containing a higher proportion of carbon dioxide than the air you breathe in. Carbon dioxide is a relatively heavy gas (nearly three times as dense as air) and so this increased amount of gas, plus the rest of the air in the balloon, will make the balloon heavier.
The proportion of pressure that a single gas exerts within a mixture?
In a mixture of gases, for example 70% Helium and 30% Oxygen, the pressure exerted will be split 70/30 between the gases, respectively. As John Dalton discovered, the proportion of these pressures is the proportion of the number of molecules of the gas within the mixture.

What is the Difference between air insulated substation and gas substation?
Air insulated means the substation is in the open air, and the dielectric strength of the air is used to isolate conductors from each other and from ground. Gas insulated means a specific gas is used for insulation; this gas is usually an inert gas such as nitrogen. Gas insulated substations, by definition, are required to be inside a contained structure, or large piping must be placed around all conductors to hold the gas.
