Frost is a physical change, the condensation and freezing of water vapor.
No, the change from dew to frost is a physical change, not a chemical change. It is a result of the water vapor in the air cooling and forming ice crystals on the surface of the windshield.
This is an example of a change in the physical states of Matter. These states-of-Matter are: Solid, Liquid, Gas and the Newest and Latest and most energetic State - Plasma. Frost is a special 'case' because it does not Condense [vapor to liquid], it Sublimes - water [in this case] vapor crystallizing [directly] to the Solid - bypassing the liquid phase.
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.
Chemical weathering involves the breakdown of rocks through chemical processes such as oxidation or hydrolysis, which alter the composition of the rocks. Mechanical weathering, on the other hand, involves the physical breakdown of rocks into smaller pieces through processes like frost wedging or roots growing into cracks.
The process is called mechanical weathering. It involves the physical breakup of rocks into smaller pieces without altering its chemical composition. This can occur through processes like frost wedging, thermal expansion, and root growth.
Hence,the formation of dew and frost is a physical change.
Frost forming on a pumpkin is a physical change. This process involves the transition of water vapor in the air into ice crystals as temperatures drop, without altering the chemical composition of the water. The pumpkin itself remains chemically unchanged, although its physical state may be affected by the frost. Therefore, it is classified as a physical change.
No, the change from dew to frost is a physical change, not a chemical change. It is a result of the water vapor in the air cooling and forming ice crystals on the surface of the windshield.

Frost on a pumpkin is a physical change. It occurs when water vapor in the air freezes on the surface of the pumpkin, forming ice crystals. This process does not alter the chemical composition of the pumpkin itself; rather, it is a temporary condition that can change with temperature fluctuations.
Frost forming on a car window is a physical change because it is a reversible process where water vapor in the air solidifies into ice crystals when it comes into contact with the cold surface of the window. The chemical composition of the water molecules remains the same before and after the frost forms.
This is an example of a change in the physical states of Matter. These states-of-Matter are: Solid, Liquid, Gas and the Newest and Latest and most energetic State - Plasma. Frost is a special 'case' because it does not Condense [vapor to liquid], it Sublimes - water [in this case] vapor crystallizing [directly] to the Solid - bypassing the liquid phase.
No, frost wedging is a physical weathering process caused by the expansion of freezing water in cracks and crevices of rocks. Chemical weathering involves the breakdown of rocks through chemical reactions rather than physical forces like frost.
Physical- that is water vapor freezing into ice. It can be reversed (warm up the window) Chemical changes don't reverse.
Yes, the change of dew to frost on a windshield is a physical property. This change involves a physical process (condensation turning to solid ice) without altering the chemical composition of the substance.
It is a physical change. When the water vapour inside of the freezer turns to frost (ice), it hasnt changed the fact that it is still water, just in a different form. Therefore, this is a physical change.
