What is the difference between steam and vapour?

Steam and vapour are quite often used interchangeably. But there is a subtle difference between the two. Look at this picture. what do you see? read more

Difference between vapour and steam is content of enthalpy, content of heat energy steam is high heated foam of a liquid, vapour is evaporated gas form of liquid , vapour heat content is very low and that depends on atmospheric pressure and temperature. read more

So the difference between vapor and steam is purely one of temperature. Water vapor (as in evaporation) is at the same temperature as the air outside. But in case of steam, water is at boiling point or higher. read more

The difference between steam and water vapor is that water vapor is typically the same temperature as the air that is present while steam is above the boiling point of water. The chemical composition of water and steam are identical. read more
