no it could be plasma
It is homogeneous, but it is not a mixture. It is an element, which is a pure substance.

No, you can only boil liquids. Boiling is process that can only be applied to liquids. A liquid will only come to a boil when the vapor pressure of the liquid is equal to the atmospheric pressure at its level of altitude.
Water can be separated into hydrogen and oxygen through a chemical change called electrolysis, which uses an electric current to break apart the water molecules. Boiling water is a physical change that only changes the state of the water from liquid to gas, but it does not separate the water into its component elements.
All of them can be gases, but under standard conditions mercury is a liquid.
Liquids can't melt. Melting is when a solid turns into a liquid. Since it is already in the liquid state, it can only evaporate, or boil.

No. Hydrogen and oxygen will only react at high temperatures.
Your Question sounds confusing but let me put it this way,most substances boil only in the liquid phase,but liquid and boiling are different
When you boil water on a stove until it turns to steam, it is a physical change. This shift occurs as water transitions from its liquid state to its gaseous state (steam) due to the application of heat. The chemical composition of the water remains the same throughout the process; only its state of matter changes.
When a melted, we say it is in liquid state. However mercury is the only metal found in liquid state.
When a liquid changes state to become a gas, it is said to evaporate or boil. The difference is that in evaporation, there isn't generally a "forced heating" of the liquid. But in either case, the atoms and/or molecules of the liquid gain so much kinetic energy that they literally "fly off" and escape the liquid state. Perhaps the only difference is in the speed of this reaction. (It's not a chemical reaction, by the way. This is a physical change.)

No. Air is a mixture mainly of nitrogen, oxygen and argon; the only four states of matter are solid, liquid, gas and plasma.

You boil a substance to evaporate the liquid.
