What happens when water vapour touches a cold surface?
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.
Why does moist in the mirror after you blow it?
The moist you are talking about is nothing but the water vapour that one releases, every time one exhales. As already know, when we breathe in, the air that enters gets humidified as it passes through the nasal passages. Hence, the air exhaled, or breathed out, contains considerable percentage of water vapour. Now, this water vapour exhaled out, initially is at body temperature, i.e., 37.5*C. On coming out through exhalation, the vapour soon cools down and condenses on the nearby mirror glass surface. Hence, the moist is seen.
What happens to the mirror when you blow it?
When you blow on a mirror, the warm air from your breath can cause the mirror to fog up temporarily due to condensation. This happens because the warm air contains water vapor, and when it hits the cold surface of the mirror, it cools and turns into water droplets on the mirror's surface.
How does vapour form on a mirror?
When warm, moist air comes into contact with a cool surface, such as a mirror, the air near the surface cools down. If the air is saturated with moisture, the cooling causes some of the water vapor in the air to condense into tiny water droplets, creating fog or mist on the mirror.
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.
Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
When the mirror turns cloudy what is happening?
water vapour in our breath is condensing on the cold surface of the mirror
Why water vapour condense on mirror?
Water vapor condenses on a mirror because the mirror’s surface is cooler than the surrounding air, causing the water vapor in the air to lose heat and transform into liquid droplets on the mirror's surface. This happens due to the process of condensation, where the water vapor transitions from a gas to a liquid state.
How the water vapour condenses on the mirror?
When the warm water vapor in the air comes into contact with the cool surface of the mirror, it loses heat energy. As a result, the water vapor cools down and changes from a gas to a liquid, forming tiny water droplets on the mirror. This process is called condensation.
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.
What happens to the energy in a substance as in condenses?
A substance condenses when it changes from a gas to a liquid. This is why we call the water you get on the bathroom mirror after taking a shower condensation - because its actually water vapour from the hot water that has then cooled down on the cool mirror.
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.
Mike is having a hot bath He notice the mirror in the bathroom is misty what is the liquid that make the mirror misty?
Water vapour
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.
Why does your mirror steam when im in the bath?
It's called condensation, steam from the hot water in the bath turns back to water when it touches the mirror covering the mirror in a thin layer of water.
Why do small droplets of water form on the mirror after you shower?
This usually happens after a hot or warm shower because the water vapour in the air becomes a liquid again. It condenses on your mirror. Condensation is taking place!
