no. mass is a constant. It can be packed into a tiny solid, or spread out in a gas form. The volume CAN be affected by heat or pressure though.

No, the mass will not change. Adding heat will make temperature go up, and increase volume if pressure is constant, increase pressure if volume is constant....all assuming a closed system.
Leave the lid off the container (open system), and the heat will give you a "mass loss" because the extra room needed by the molecules allows them to escape.

Depending on what level you're talking about, yes, heating will add a small amount of mass, it increases the energy of the system and consequently the mass via del-E = del-mc^2. But this is usually negligible compared to the mass of the system originally, unless you're talking 1000s of degrees K

If you look up Boyle's Law, you'll see that only temperature, volume, and pressure are related.
If this is a Chemistry question, then the answer is no.
If this is a trick question in your Physics class, then under extreme conditions, fusion can occur, either decreasing (usually, for atoms lighter than iron) or increasing the mass. But mass-energy still does not change.

Mass can't change unless you add or take away some of the gas.

no...as long as you do not add or reduce any molecules, it will stay the same
