There is so much space between gaseous particles that the particles rarely bump into contact with each other. Water can move through the three states of matter depending on temperature. It can be found as a solid in ice, liquid water and as a gas in water vapor. Consider the flow diagram below of how the states of matter phase into each other; the processes by which this happens are named:.
Notice that the condensation process is when a gas turns into a liquid. With water, this means water vapor has turned into liquid water. A condensation chemistry definition is the process of a substance changing from a gaseous to a liquid state. This process is caused by a change in mostly temperature, but also pressure. Also recall how the molecules acted in both the gaseous and liquid states.
In a gas, particles have a high kinetic energy. In a liquid, they have less kinetic energy. Good loft insulation prevents heat loss and the snow remains on the roof of well insulated homes longer.
Poorly insulated homes can be seen with little or no snow upon them. External condensation usually occurs at certain times of the year under particular weather conditions. This is usually when the seasons change from winter to spring and autumn to winter. This usually results in warmer days and cooler nights. The overnight drop in temperature cools the outer pane and gives an area for moisture to condense on to should the humidity be at appropriate levels.
This can be due to the aspect of the window. Northern facing aspects often experience higher levels of external condensation because they get no direct sun in the morning which usually evaporates the condensation. Also, sheltered windows, such as one side of a bay window near a porch for example, can have condensation whilst a window in the same bay may not.
Normally the external condensation is short lived and only occurs on cool mornings. Often it may have evaporated in the early hours before a homeowner opens the curtains and never be seen. In extreme circumstances as in sheltered northern facing aspects, with a cool night and high humidity, the condensation may occur more or stay longer.
Anti-condensation glass has been developed and can be specified but this will only reduce the occurrence and levels of condensation and not eliminate it.
This stems from condensation on the glass surface and the appearance of various shapes within the condensation. During manufacturing, the glass is moved around by our flat glass supplier in sheets measuring approximately 3m x 6m and processed in to approximately 3m x 2m sheets that we can handle and move around our factory. This transportation is mainly done using suction cup transporters that allow the picking up of large cumbersome sheets of glass without damage or risk to both staff and glass.
This is a vacuum suction cup and can be various sizes and shapes depending in the process being done. Some are circular and around dinner plate size possibly 6 circles in 2 lines of 3, or smaller saucer sizes.
Our processing equipment has some oval shaped cups that again move and hold the glass whilst processing. Post processing includes the application of an identification label that is rectangular measuring approximately 12cm x 8cm and protection pads approximately 2cm x 2cm.
All these processing, identification and protective items may leave slight residue on the glass surface. Air has water vapor in it, and the amount of water vapor that is stable in the air depends on temperature.
Cool it off to where there is too much water vapor, and the vapor will condense out to form droplets, either on a cold surface, or just in the air that's what clouds are. Heat the air or the water to the point where any amount of vapor in the air is stable, and the water will boil.
The drops come from the surrounding atmosphere. Because colder air causes condensation at a higher rate that warm air, water vapor contained in the surrounding warm air condenses out when it comes in contact with a colder cup. When a cup is cold, and creates condensation, where does the drops of water on the outside of the cup come from?
Answer 1: The water drops on the outside of the cup come from water that's already in the air. Answer 2: The drops of water on the outside of a cold cup come from the air. Great question and observation! Answer 3: The water comes from the surrounding air.
Try this experiment to see if you can figure it out! There should be moisture on the outside of the cup that was exposed to the air and much less moisture on the outside of the cup that was in the bag. Most air, except for in very dry places, has water molecules mixed in with the other molecules that make up the air.
When water molecules in the air get cold, they slow down, join together, and become tiny drops of liquid water. This process is called condensation. This is what happens when water molecules in the air touch the outside of the cold cup that is exposed to air. Not much air touches the cup in the bag so not much moisture can form on it. The inside top surface of the cup with the ice should have more and bigger water drops on it than the top inside surface of the cup without the ice.
The inside of each cup should have a lot of water vapor in it from the evaporating hot water.
