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.
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.
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.
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.
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.
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.
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.
water vapour in our breath is condensing 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.
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.
The steam condenses to form water droplets on the cooler surface.
it becomes water vapour in the air
Steam is water vapour - just a very hot form of it.
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.
Water vapour
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.
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.
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!
