25ml of pure water at room temp is about 1g/ml so 25g.
number of moles = mass over molecular mass, molec mass or h2o is 18.
25/18 is 1.389 moles.
1.389 x avagadros number (6.022x1023) = 8.3645 x1023 molecules
8,364085819.1023 molecules in 25 g of water
Conservation of mass here. 25 grams.

No they are not the same. Steam is formed when water reaches boiling point then the water will start to evaporate to make water vapor. They then join particles in the air. Whenever there is a cold surface nearby the water will hit it and condense. Mist is formed when the ground cools and cools air close to it it causes condensation an water droplets form in the air.
WELL! moist heat is used by heating with steam and the steam can not be formed below 100oC so it is not possible to kill microorganism by moist heat below hundred degree
in a physical change, no new substance is formed. for example liquid water. You freeze it, it becomes ice. when you boil it, it evaporates into steam. HOWEVER. Steam, ice, or liquid, it is STILL water. You only form new substances in chemical changes: cooking/burning food, reacting chemicals etc. : )
The Oreck Steam It is a popular steam cleaner for all types of surfaces. Sienna Aqua steam cleaner is a close second with consumers.
Steam rising from coffee
There is no mass loss (nor gain) in state change, so there would be 100 grams of ice formed.

Steam
A gas called water vapour is formed, it is steam.
Water is formed as a liquid when steam meets a cold surface.
It's not difficult.Steam is formed when water evaporates.
Yes, it can.
steam is created by vaporisation of the water on the ground or in a kettle.
The steam (vapors) is also water - H2O.
The bubbles evident in a pot of boiling water are pockets of steam created by adding heat to the water. Bubbles form as a result of the surface tension of the water containing that steam. Without that surface tension, individual molecules of steam would merely escape from the surface of the water directly and no bubbles would be formed. Steam expands approximately 1600 times from the volume of the water from which it is formed.
