The formation of water drops on the outside of a glass is a physical change. This occurs due to condensation, where water vapor in the air cools and changes into liquid water when it comes into contact with the cold surface of the glass. The process is reversible, as the water can evaporate back into vapor when the temperature rises. Therefore, it does not alter the chemical composition of the water.
Condensation
Yes, adding salt to water increases its density, which may affect the surface tension of the water and impact the number of drops that can balance on a coin. The increased density can lead to smaller drops forming, potentially allowing more drops to balance on the coin due to the altered properties of the saltwater solution.
When you have a glass of cold water from the fridge that you take outside, because it's hotter outside, little drops of water will form on the glass.
Condensation will collect on the outside of the beaker when you put a 5 ml of water and ice cubes inside due to the temperature difference between the cold contents inside the beaker and the warmer air outside. This causes water vapor in the air to condense, forming droplets on the exterior surface of the beaker.
it's condensation
This is a physical change.
The cause is the condensation of water vapors.
Condensation
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.

Frost is a physical change, the condensation and freezing of water vapor.
