How can you tell that the melting of ice cube is a physical change?

You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.

How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Is melting of glass a chemical or physical change?
Physical change because no new substance is created.
When ice melts you can tell it is a chemical change because?
The melting of ice is a physical not, not a chemical change. You can tell this because the chemical composition of ice and water are exactly the same, i.e. they are both H2O. Only the physical property has changed since one is a solid and one is a liquid.
Which is not a physical property of a substance melting point density solubility rusting?
well if you dont know the (answer) i can tell you the answer is rusting because it is a chemical change you should always remember it is a chemical change and not a physical change
Why is ice cream melting a physical change?
Melting is a change of state. Technically you could chill it again and change it back to icecream. You'd just have to have it churning to keep it mixed correctly. Now, if it spoils, then that is a chemical change! You can tell by a change in color, smell and inability to change it back to its original state.
How do you tell if a frozen turkey is defrosted?
There is no weight change. Think of an ice cube melting, does it change weight?
Is the burning of leaves or melting of butter a physical reaction?
The burning of leaves is a chemical reaction. The way we can tell is because after the leaves are burned, they cannot go back to the way they were. Butter melting is a physical reaction because it does not change the molecules, and the butter has the ability to go back to it's original state.
Why is melting of ice cream a physical change?
Chemical Change!Because when chocolate start out as just chocolate but when it melts it becomes a chemical because its just something to drink like water,Water is a chemical beause its just something to drink,but you don't actuly drink chocolate,it just becomes a chemical because it melts in to a liquid and all liquids are just becomes a solid,so Chocolate is a chemical when it melts because its just like water but chocolate isn't water its just like water because it melts into a chemical!
Is melting wax a physical chemical or nuclear change?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Whats a physical change?
A physical change changes the property of a substance without changing the substance completely. In other words, a physical change is reversible.This change that occurs in the physical property/properties of a substance without altering its composition. A physical change:Possibly canchange withstate of matter (sublimation, decomposition, evaporation, melting, freezing, and condensation).No new material is formed.Possibly can dissolve.Possibly can occur either by increasing or decreasing the temperature.Is reversible.A physical change is any change not involving a change in the substance's chemical identity.a physical change is the color shape taste and smell of a substance.A physical change is where an object changes is size/ shape
What are some examples of physical properties scientist use to tell the differences between substances?
Melting point and boiling point are two physical properties that can be used to tell the difference between substances.
How is the physical change in the robot reversible and how can you tell that the change follows the law of conservation of mass?
Most physical changes are reversible it’s part are just rearranged
