Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
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.
This is a physical process.
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.
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 hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
This depends. Are the pot noodles dry at room temperature? Then not yet .Are the pot noodles in boiling water? Is the water you are adding from the cold water tap? Then, Yes, as boiling will stop until the new water is at boiling temperature.
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.
This is a physical process.
The process of adding dish soap to water in a sink is a physical change.
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.
Adding water (which is not a reactant) is a physical process.
No. It is a physical change.
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.
