Is formation of dew and rain a physical change?
Formation of dew and rain is not a chemical change, but a physical change. Often a change involving state of matter like in this case condensation (or like evaporation, melting, freezing, sublimation, or deposition) shows a physical change and not a chemical change.
Is hail a physical change or chemical change?
Hail formation is a physical change. It involves the freezing of water droplets in clouds into ice pellets, which then fall to the ground. This process does not involve a chemical change in the composition of the water molecules.
Is hard water staining pipes a physical change?
Formation of these salts is a chemical process.
Is reactivity with water a physical or chemical change?
This is a physical change. The bubbles are pockets of steam which is the same chemical as water, just in a different state.
Is balls of wax forming when melted wax is poured into ice water a chemical change?
No, the formation of balls of wax when melted wax is poured into ice water is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of the substance, which is not occurring in this case.
When icicles form at the edge of a roof is it a physical or chemical change?
The formation of icicles at the edge of a roof is a physical change. It occurs when water freezes due to a drop in temperature, without any change in the chemical composition of the water molecules.
Is icicles forming at the edge of a roof a chemical or physical change?
Physical. (Its still water.)
If tap water and soap form an insoluble deposit is this a physical or chemical change?
The formation of an insoluble deposit when tap water and soap are mixed is a physical change, not a chemical change. In this case, the molecules of the soap and tap water are simply rearranging themselves to form the deposit, without any new substances being formed.
Is icicles from at the edge of the roof physical or chemical change?
Icicles is solid water (H2O); formation of ice is a physical process.
Is it a physical change chemical change when salt dissolves in water?
Physical
Is steam from a kedal a physica l or chemical change?
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
Is steam turning to water a chemical or physical change?
The formation of steam is a physical change. The chemical composition of steam (water vapor), is H2O, and the chemical composition of liquid water is H2O, so there is no chemical change going from liquid to gas (vapor/steam). Thus, it is a physical change.
