A mirror is likely to turn cloudy if you breathe on it. The moisture on your breath condenses on the cold surface of the 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.
I think you are refering to "dew".
When water vapor hits a cold atmosphere, it condenses into tiny water droplets or ice crystals, leading to the formation of clouds. This process is known as condensation and is the first step in cloud formation.
You can demonstrate that you breathe out water vapor by exhaling onto a cold surface, such as a mirror or glass. The moisture in your breath condenses upon contact with the cold surface, forming tiny droplets that create a foggy appearance. Alternatively, you could use a hygrometer to measure the humidity in your breath, showing the presence of water vapor.
When steam condenses onto a cold mirror, the water vapor in the steam loses energy to the cold surface of the mirror. This causes the water vapor to change phase from gas to liquid, forming water droplets on the mirror's surface.
When steam in the bathroom hits a cold surface like a mirror, it condenses into water droplets. This is because the cold surface causes the steam to lose heat energy, changing it back into liquid water.
When steam in the bathroom comes in contact with a cold surface like a mirror, it loses heat energy rapidly to the cold surface. This causes the steam particles to lose energy and slow down, leading to condensation. As the steam cools and condenses, the liquid water droplets adhere to the mirror's surface, causing it to fog up.
When steam (water vapor) comes in contact with a cold mirror, it loses heat energy to the mirror. As a result, the water vapor particles slow down and come closer together, transitioning into liquid water droplets. This process is called condensation, where the gas phase (water vapor) turns into the liquid phase (water droplets) due to the loss of thermal energy.
A mirror is likely to turn cloudy if you breathe on it. The moisture on your breath condenses on the cold surface of the mirror.
It provides heat to the surface it condenses to. That is why gas condenses on cold surfaces.
No. The steam from a hot shower fogs the mirror.
It really depends on the temperature of the steam and temperature of the cold surface. 250 degree steam hitting a 50 or 60 degree surface will just turn back into water and droplets can be seen almost immediately. 1000+ degree steam hitting a frozen surface may cause a loud bang and eventually turn back into water.
Water vapor in your breath condenses when it contacts cold air. (It looks like steam.)
When the warm air from your lungs meets the very cold air of winter it condenses into visible water vapour. This is the steam you see.
Cold air holds less moisture than warm air. When you run the shower with hot water, the moisture condenses on the cold mirror surface causing it to fog up. If you run the shower cold, the mirror will not fog up.
When steam hits a cold surface, it condenses back into water droplets, causing a mist or fog to form. This occurs because the cold surface lowers the temperature of the steam, making it lose its heat energy and turn back into liquid form.
