This is a physical process.
Cooking noodles is a physical change because the noodles undergo a change in state from hard to soft through the absorption of water and heat, without forming new chemical compounds.
Adding water (which is not a reactant) is a physical process.
Making water glow is a physical change. Adding a substance like a fluorescent dye or phosphorescent material to water to make it glow involves only a physical alteration in the properties of water, not a chemical change in its molecular structure.
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
Adding water to pot noodles does not result in a physical change, as the water is simply being mixed with dry ingredients to rehydrate them. A physical change involves a change in the appearance or state of a substance without altering its chemical composition.
This is a physical process.
Cooking noodles is a physical change because the noodles undergo a change in state from hard to soft through the absorption of water and heat, without forming new chemical compounds.
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
The salt kills germs on the noodles.

Physical because, the lemonade dissolves into the water, without creating any of the chemical changing results.
Mixing cornflour and water to form a paste is a physical change. This change does not alter the chemical composition of the cornflour or water, only the physical state of the mixture. When the paste dries, it can return to its original components by adding water back.
