Is it a physical or chemical change when water goes over a waterfall?
It is a physical change, because you are not making a new substance.The water is still staying water, and it is reversible, because if it is making clouds, the clouds become rain, and the rain can then evaporate or the clouds themselves can evaporate.
Why is the formation of clouds a physical change?
Clouds are formed by water vapors condensations. And the processes implied in the formation of clouds (evaporation, condensation, freezing) are all change of matter - physical changes. A chemical process need a change in the nature of the chemical reactants - but in this case the chemical formula of water (H2O) remain the same.
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 rain turning to sleet a physical or chemical change?
A physical change. It came from water and is still water.Physical - the water changes from a gas,water vapour, to a liquid, rain.
Is the formation of clouds a physical or chemical change why?
Clouding is a purely physical process of condensing vaporous water into liquid water (also freezing or sublimating it to solid ice / hail / snow) . Chemically nothing has changed (water molecules stay unchanged, still being water) only there (physical) state (this is a kind of 'condition' of matter) has changed.
How Cloud forming in the sky a physical change?
Its a physical change because when clouds form, water vapor condenses into water crystals. That is a phase change which is also a physical change.
Chemistry equation fro precipitation?
Precipitation is not a chemical change, but a physical change. The chemical involved is water, and this condenses and cools in the sky to form clouds which become denser and the droplets of water larger until they fall from the sky as rain. The only chemical involved is water.
Are clouds a physical or chemical change?
Physical because no reaction is taking place.
Is clouds forming in the sky a chemical or physical change?
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
How and why is clouds forming in the sky a physical change?
because condensation is simply just a change of the water temperature in the air. a temperature change is a physical change. clouds form when the water vapor condenses, so therefore, cloud formation is a physical change.
Piece of lemon turing tea cloudy chemical or physical change?
Chemical The acid in the lemon clouds the water and the elements combine.
Chemical is caused by acidic rain?
sulphur dioxide condenses in the clouds, then it falls with the rain. PH 4

Evaporated water condenses in the atmosphere to form what?
Evaporated water condenses in the atmosphere to form clouds.
Is formation of clouds is chemical?
The formation of clouds is a physical process, not a chemical one. It involves the condensation of water vapor in the atmosphere as it cools, leading to the tiny droplets that make up clouds. While there are chemical processes at play in the atmosphere, the initial formation of clouds is primarily a result of physical changes in temperature and pressure.
