Why is water freezing into ice a physical change?
You can always undo a physical change by reversing the process. i.e. when you freeze water it turns into ice and when you heat the ice it turns back into water. Therefore it is a physical change.
Is the melting of ice is a chemical or physical change why?
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
A popsicle melting is physical or chemical change?
Melting is a physical change.
When a substance change from one physical form to another you say the substance has had an?
When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
Is physical reaction the same as physical change?
No, physical reaction and physical change are not the same. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition, such as melting or freezing. A physical reaction, on the other hand, refers to a process where no new substances are formed, such as dissolving salt in water.
Why is it a physical change when ice melts to liquid water?
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
True or false When frozen water melts it is undergoing a physical change?
Actually it is undergoing a crappy change.
What does it mean to say a physical change is reversible?
A physical change is reversible if the substance can return to its original state after the change has occurred. This means that the change does not alter the chemical composition of the substance, allowing it to be reversed through processes like melting, freezing, or evaporation.
Can Physical changes change back into their original form?
I say yes becuse for example if you freeze water it will turn into ice then melt then melt back into water.ps add jj serrano on facebook
Is crystallization of salt a physical change?
Assuming you're talking about salt forming as water evaporates: yes, that is a physical change. If you mean salt crystals forming from the combination of sodium and chlorine, then that's a chemical change.
