condensation. the glass is cooler inside than it is outside (you mean drinking glas right?)

this temperature difference creates what is called condensation to form on the outside of the glass.

The inside of the glass is cold while the warmer moist air is on the outside creating condesation.The water comes out of the air.When you boil water the steam you make goes into the air as a gas and becomes part of the atmosphere. When air is cooled it becomes less able to hold this water and the water condenses out of the air as little droplets - this is what clouds are and how rain forms.The cold can cools the air next to it and the water in the air condenses into drops on the outer surface of the can - in the process the can and the pop inside are warmed up.It is condensation from the air. In the air there is water gas. This gas freezes when near a cold container. It then sticks to the jar which creates the wetness you see.The liquid water on the outside of the glass comes from the air. Since the glass is so cold because of the substance inside of it being cold it makes the surrounding air close to it colder.

The expansion of the glass makes it break (the inside of the glass, which is in contact with the hot water, tries to expand more than the outside; the tension makes the glass break).


A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.


the heat makes it expand you see


A liquid has no definite volume because if you pour it into a circle glass and then pour it into a square glass it will still be a liquid. A solid has a definite volume and definite shape and gas has no definite shape or no definite amount.


Clouds are large quantities of water vapor. This is the gaseous form of water and is what makes up clouds.


The water molecules in the air around us sticks to the outside of a glass, can, cup etc when the cold of the liquid inside decreases the temp of the object its in, makes those water molecules expand and starts "sweating."


Glass fiber is drawn from a boule of glass that has had its outside surface heat treated. That makes a fiber that will not allow the light to leak out.


well most things in the world start as a liquid. What most do is but in a "glass oven" it harden in the mold and you have the glass that you see today. In other words is it goes from liquid to solid. please pass your wisdom on . . . Wise woman age 9


No, heating a liquid makes it's particles move farther apart (makes the liquid expand). This is most readily observed in an old glass thermometer. As your temperature goes up (as you heat the liquid in the thermometer), the liquid inside expands and travels up the thermometer.


"Evaporation" changes a liquid to a gas. Energy (from the sun... or the burner on your stove) heats up the water, speeding up the movement of the molecules until they bounce so far apart that they become a gas and "evaporate" into the air."Condensation" happens when the temperature of the moist air (containing evaporated water) cools, making water molecules to stick to whatever they can find (like dust... or the outside of a cold glass). Condensation makes a cloud. Once enough condensation has happened and the droplets of liquid water are heavy enough, they fall to the ground as rain or "precipitation".


Cohesion and Adhesion. Adhesion is the property of water that makes it stick to other substances. For example, water on glass. Cohesion is the property of water that makes water stick to itself. For example, water droplets. Now you breath and the air has trace amounts of moisture, so when you breathe out, the moisture go from your mouth to the glass, and due to adhesion, it stays there for a while.


the coldness of the ice water makes condensation, and so the condensation appears on the outer coating of the glass.


the cold glass cools the air in contact with the glass to the point that it can no longer hold as much water vapor as is present. This makes water condense on the outside of the glass. or more formally The vapor pressure of water at the temperature of the glass is less than the partial pressure of water vapor in the surrounding air causing condensation.


Yes. The three common phases of matter, solid, gas and liquid can be achieved by any material provided the right conditions, but different materials exist in different phases under the same conditions. The most common way that changes between these phases are achieved is by a change in temperature (although a change in pressure will also affect the state of matter). If a gas is cooled sufficiently, it will form a liquid. For example, if you set a glass of ice-water out, the outside of the glass will become wet. This wetness is water vapor which was in the air as a gas, but was cooled when it came into contact with the cold glass and condensed on the glass into a liquid. Even gases like Nitrogen, which makes up most of the air around us, can form a liquid, although it must be cooled to −196 °C.


A person who makes glass is a glassmith if that helps


Because the water evaporates outside of it and makes it sticky and cold. A2. The surrounding air contains water vapour, but can only hold so much for a given temperature. The cold of the can, causes the air touching it to cool. The air cannot hold the water at this cooler temperature, so it comes out, as water droplets on the can. So the water comes from the air.


What makes a liquid a liquid is the resistance to compression. There are a number of molecules, ions and atoms that make up liquids.


Yes, solid water (ice) is more dense than liquid water. This is what makes ice cubes float to the top of a glass.


Glass is Crystaline SiO2



It has an internal blockage! Air conditioning gas cools as it expands (as it changes from liquid to a gas). It is meant to be a liquid in your condenser but if your condenser has a blockage (say some dirt or other contaminent) then the liquid loses pressure on the other side of the blockage and becomes a gas. This makes your condenser really cold and frosty on the outside!


Air conditioners use the physical properties of compressing gas into liquids and letting these liquids decompress back into a gas. When you compress a gas into a liquid, heat is formed. When you decompress this liquid, cold is formed. Your AC compresses gas outside the house (makes heat) and then lets the compressed gas (liquid) enter into the house side of the AC. On the house side, the liquid is decompressed (makes cold). The decompressed gas goes back outside the house and the process is performed over and over again.


A mild flame can make glass black.
