Exterior light fixtures can be a big problem because they may penetrate the air barrier, which compromises the heated envelope of the light house. However, the worst fixture is a recessed light that penetrates an attic.

yes it has to be heated in water in a supersaturated solution.
when copper and zinc are heated, they create brass :)
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
No, not unless the screen or filter is heated
No. A hot air balloon is a solid object. That is, the basket, the ropes, the burner and the envelope itself are not gasses. The air within the envelope is a gas, of course; heated atmospheric gasses in fact. But the balloon itself is not a gas.
Actually, nothing is heated to create cement. Cement is a mechanically bonded combination of cement, sand, water, and gravel (aggregate).
In a nutshell, air rises and expands when heated. Through the use of a burner the balloon pilot heats up the air inside the envelope (the balloon itself), this air inside the envelope expands and rises, lifing the basket.
To create an electron cloud that can be shaped into a beam.
Using polyethenes to create polymers which is then additionally heated to become plastic cards.
