Why are droplets of water that form on a cold glass a physical change?
Angiegrange
The formation of water droplets on a cold glass are a physical change because it's nothing more than condensation. The water that is in the air is a gas, and it has undergone a change of state to become a liquid (the droplets). If the water and the glass fused and made another element that could not be made back into either of its two original forms, then it would be a chemical change.

∙ 11y agoThe change of state of matter of WATER from vapour (humid air, water vapour) to liquid (condense, droplets, mist) is a physical change, the reversed can easily (and repeatedly) be done by raising the temperature. No substance is changed in properties: water stays water, even iced (frozen water) it is still water.

Why there is water droplets forming on mirror when blown?
The hot heat from the hot water turns evaporates. Once it reaches or touches a cool surface (mirror), the heat would condense and turn into water droplets. Therefore, water droplets are found in the mirror when you bath.
What physical property of glass would help you to separate the broken glass from water?
Broken glass is a physical change because the glass does not undergo any chemical changes by being broken. The glass could be returned to its original shape through physical means (melt and reform it). Glass is mostly silicon oxides, and the chemical bonds between the silicon and oxygen (which comprise the bulk of common glass) are not affected by breaking the glass.
Is mixing lemonade powder into water a chemical or physical change?
Mixing lemonade powder into water is a chemical change. This is because the powder changes the water molecules and can not be taken out.
What is it called when droplets of water form on the outside of a cold soda can?
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.
Is the melting of ice a physical change or a chemical change?
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
Is water freezing to form ice a chemical or physical change?
well ! actually it is a very simple phenomenon.....because of the icy cold water, the air around it gets condensed when it comes close enough. consequently, the condensation causes the water vapors in the air to change into droplets that then appear on the surface of the container of that icy cold water...
Is a bathroom mirror fogging as someone showers a physical or chemical change?
Physical, it is water vapor condensing on the colder glass of the mirror.Physical
Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
Is salt dissolving in a glass of water a chemical change?
No. It is a physical change.
Is possolving table salt in a glass of water a physical change of a chemical change?
It is a physical change because the chemical composition of the salt and water does not change.
What do the water droplets on a glass indicate about the temperatures inside and outside the terrarium?
the water droplets indicate that the air is cooler on one side of the glass. If the droplets are inside, then the outside is cooler. If the droplets are outside, it means the inside is cooler.
Is a broken glass of water on the floor a physical or chemical change?
If it is resting on the floor, there is no change at all.
Is a hot glass cracking when placed in cold water a physical change?
it is a physical change because the state of the glass does not change.it cracks because of the rapid change of temperature
Is on a hot day drops of water collect on the outside of a glass holding iced tea a physical or chemical change?
Drops of water collecting on the outside of a glass holding iced tea is a physical change not a chemical change. It is simply atmospheric moisture condensing on the cold glass. Condensation is a physical process.
What happens if water droplets fall on the hot lighted bulb which is ON?
If the water droplet is big enough, the glass will shatter from the fast change in temperature.
What is the water droplets on the side of the glass called?
Condensation
What does collect on mean in chemistry?
collect: gather such as water droplets colllected on the flask as the water evaporated. This represents a physical change rather than a chemical change.
