Why there is water on glass when ice melts?
because the water vapour in the air touches a cold surface such as glass and then turns back into water on the cold surface and this process is called condensation
What happens when you breathe on a window and water droplets appear?
The water vapour in your warm breath condenses back into water on contact with the cold surface of the window.
What happens when potassium is allowed to burn in bromine vapour?
you will get potassium bromide
What is the difference between a gas and a vapour?
A gas is the normal state for a material at given temperature while a vapour is made from some particles that have escaped from the liquid surface.
Process in which vapour molecules are recaptured by molecules at liquid surface?
I suppose that dynamic equilibrium is the adequqte term.
What happens when water vapour touches a cold surface?
melt
What is the chemical or physical explanation for why water explodes when tossed on a grease fire?
Because as soon as water touches the hot surface, the bottom part, where the water touches, changes to vapour instantly! this happens so fast, that when it expands, it expands with explosive force and even pushes the water on top of the vapour outwards. this may carry some oil with it.
Why there is water on glass when ice melts?
because the water vapour in the air touches a cold surface such as glass and then turns back into water on the cold surface and this process is called condensation
How the water changes froim gas to liquid?
Water vapour (commonly referred to as steam) is turned back into liquid by a process of condensation. When the warm vapour touches a cold surface (a window pane, for instance) the vapour cools and forms droplets of liquid water.
What happens to water vapour when it evaporates from the earth's surface?
When water vapor is evaporation outside it rises to the sky and goes through the water cycle.
What will happen when the evaporating dish has been covered with an inverted funnel upon heating?
Anything evaporated would be funnelled upwards where the vapour could be collected if a tube was to be fastened to the funnel .
How the water vapour condenses on the mirror?
The surface of the mirror is cooler than the surroundings. When the water vapour comes into contact with the surface of the mirror, they condense.
Why a glass of cold water perspires with water drop when exposed to air?
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
What happens when you breathe on a window and water droplets appear?
The water vapour in your warm breath condenses back into water on contact with the cold surface of the window.
What happens if vacuum is 10 mm Hg in Vapour absorption machine?
what happens if vacuum is 10 mm hg in vapour absorption mechine
Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
What is the process that happens when a vapour is cooled?
It's called condensation when vapour cools and turns into liquid.
