Is hard ketchup a physical or chemical change?
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.
When dew on a windshield changes to frost is that a chemical 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.
Melting a nail physical or chemical change?
Melting a nail is a physical change because only the state of matter is being altered, from solid to liquid, without changing the chemical composition of the nail. The nail can solidify again by cooling, showing that the change is reversible.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Is melting paper clip a physical or chemical change?
Melting a paper clip is a physical change because it does not alter the chemical composition of the paper clip. The paper clip simply changes from a solid state to a liquid state and can be reversed by cooling it back to a solid.
Is cooling a coke in ice physical or chemical change?
physical
Is cooling liquid water to form ice a chemical change?
No. Freezing is a physical change.
Is burning a tortilla chemical or physical change?
Chemical; you are changing the physical properties of the tortilla. Physical would be just warming or cooling it for example
Is it physical or chemical change a candle wax falls on the ground and cools?
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
Is lava cooling into lava rocks a chemical change?
No. This is simply a change of state from liquid to solid. It is a physical change.
Is vapor a chemical change?
no as it can be turned back to water or be freeze to ice by over cooling.
Is hard ketchup a physical or chemical change?
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.
When dew on a windshield changes to frost is that a chemical 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.
Is the vaporization of a liquid to a gas a chemical change?
No, it's a physical change. Because we can change these vapours to liquid again by cooling.
Is cooling a drink by putting an ice cube in it a chemical reaction?
No. The ice melting is a physical change.
Melting a nail physical or chemical change?
Melting a nail is a physical change because only the state of matter is being altered, from solid to liquid, without changing the chemical composition of the nail. The nail can solidify again by cooling, showing that the change is reversible.
Why is hot soup cooling down a physical change?
The chemical composition remain unchanged.
