Why is steam so powerful?
The water is still nearby, but it’s now in a gaseous form called steam. This form of water is also called water vapor, and it’s very powerful stuff. This is because steam has a lot of energy . ... This is because as you continue to add more heat, more water molecules turn to vapor, and then you’re not heating them anymore!
Is water vapor a gas?
Water vapor is the most important greenhouse gas . It controls the Earth’s temperature.” ... If a volume of air contains its maximum amount of water vapor and the temperature is decreased, some of the water vapor will condense to form liquid water.
What’s the difference between water vapor and steam?
Water vapor is water as a gas , where individual water molecules are in the air, separate from each other. Steam is what you see above a boiling kettle. Steam is hot water in droplets almost big enough to see – but you can see the cloud of droplets.
