When water vapor touches a cold surface, it condenses and turns back into liquid water. This occurs because the cold surface causes the water vapor to lose heat energy, leading to its transition from a gas to a liquid state. This process is known as condensation and is commonly observed on windows or mirrors.

What happens when water vapour touches the mirror?
When water vapor touches a mirror, it condenses into liquid water due to the temperature difference between the vapor and the mirror surface. This condensation creates a thin film of water droplets on the mirror's surface, causing it to appear foggy or misty.
Why a glass of cold water perspires with water drop when exposed to air?
When a glass of cold water is exposed to warm air, condensation occurs on the surface of the glass. This happens because the warm air cools down upon contact with the cold surface of the glass, leading to the water vapor in the air condensing into liquid water droplets. This is why you see water drops forming on the outside of a cold glass.
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.
Why you can see vapour on the surface of ice in winter?
When warmer air comes into contact with the cold surface of the ice, it causes condensation of water vapor in the air, forming tiny water droplets that appear as mist or fog on the surface of the ice. This effect is similar to what happens when you see your breath on a cold day.
When blowing across the top of a glass of iced tea on a hot summer day a person may see a faint white vapour This happens because water vapour in breath?
This happens because the warm air from the person's breath hits the cold surface of the glass, causing the water vapor in the air to condense into tiny droplets that appear as a faint white mist.
What happens when water vapour touches the mirror?
When water vapor touches a mirror, it condenses into liquid water due to the temperature difference between the vapor and the mirror surface. This condensation creates a thin film of water droplets on the mirror's surface, causing it to appear foggy or misty.
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.
Why a glass of cold water perspires with water drop when exposed to air?
When a glass of cold water is exposed to warm air, condensation occurs on the surface of the glass. This happens because the warm air cools down upon contact with the cold surface of the glass, leading to the water vapor in the air condensing into liquid water droplets. This is why you see water drops forming on the outside of a cold glass.
Why there is water on glass when ice melts?
Water forms on the surface of the glass when ice melts due to condensation. As the ice melts, it releases water vapor which comes into contact with the cooler surface of the glass, causing it to condense and form water droplets.
What happens to water it evaporates?
it becomes water vapour in the air
What happens to steam before it becomes water vapour?
Steam is water vapour - just a very hot form of it.
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 chemical or physical explanation for why water explodes when tossed on a grease fire?
When water is tossed on a grease fire, the water quickly turns into steam due to the high heat of the fire. The steam expands rapidly and displaces the burning oil, causing it to splatter and spread the fire. This explosion is due to the rapid vaporization of water and the mixing of steam with hot oil, creating a volatile reaction.
Why are there water droplets form on the window of an air-conditioner bus?
The interior of the bus is cooler than outside the bus because of the air conditioner. Water vapour outside in the air touches the cooler surface of the window of the bus and condenses to form water droplets on the window.
What happens when steam from a kettle or hot shower touches a cool tile or mirror in what way is water changing its state?
The steam condenses to form water droplets on the cooler surface.
When it reaches the atmosphere what happens to rainwater?
it becomes water vapour in the atmosphere.
