Heat.
Condensation
Vaporization. Exaporaization and boiling are examples of vaporization.
The water level DECREASES because: As you boil water, the bonds between water molecules are broken and they turn into gas. The water vapor rises leaving less liquid water then there was before.
Excess air being excreted from the compound it came from.
Water is water, whether solid (ice), liquid or gas.
The sun can turn water into a gas through a process called evaporation, where the sun's heat causes water molecules to escape the liquid phase and become water vapor in the air.
water vapor (gas state) can turn into water (liquid state) when cooled.
To turn off the gas on your water heater, locate the gas shut-off valve near the unit and turn it clockwise to close it. This will stop the flow of gas to the water heater.
Condensation
This gas is formed from water vapors.
It can turn to gas / steam might be considered a type of gas
Vaporization. Exaporaization and boiling are examples of vaporization.
Water turns into water vapor, which is a gas, when it evaporates.
Vaporization (evaporation) of water to a gas is caused by heating the water.
A gas can't turn directly into a solid but a solid can turn into gas for example ice to water vapor.
Heat
Heat. The addition of heat causes expansion and spreading of the molecules which in turn causes an increase in pressure.
