Gas dissolves in water, this would include the oxygen and nitrogen in the air. As water is heated it loses it's ability to hold onto the dissolved gasses. This is why ice cubes made from tap water fresh from the tap freeze cloudy, but if you use boiled water from the kettle the ice freezes clear.
No. But to be fair when you said water contains 50% air you didn't specify if you meant be volume, molar quantities etc. It's still only a little bit and not really where the gas comes from in your radiators (maybe a tiny contribution the first time you fill it up and bleed the rads, but once it's been hot most dissolved gas will escape. The system is sealed so that water doesn't escape, air can't get in unless you have a wet carpet or empty header tank.
