Question

How is steam produced?

Answer 1

///////

steam is produced through evaporation , heat gain in water causes change of state from liquid to gas

Answer 2

its by evaporating water.

Answer 3

Evaporation

Duh!

Answer 4

boiling....where there is a change of state from liquid to gas...

Answer 5

Steam is water in the gaseous phase(that we can see, and  usually refers to hot). To get from a liquid to a gas energy must b added. Evaporation occurs on the surface. It is increased by increasing the surface area, removing the saturated air over the water(wind) . Water can evaporated below the boiling point. Boiling is when the change is occurring all the way through at the same time. Steam used in industry for electricity generation is made by boiling water using heat of varied sources of fuel.

Answer 6

energy is added to water (ie, it is heated). The energy excited the molecules and they undergo a phase change from liquid to gas.
