Is evaparation a physical or chemical change?
Physical. If water evaporates, it is still water. It does not change into a different substance. A Chemical change is when something changes into a different substance. For example, when wood is burned, it changes into a different substance(ash).
Can a physical change change what a substance is Explain your answer by giving an example?
No, a physical change does not change what a substance is; it only alters its form or appearance. For example, when ice melts into water, it remains H₂O in both solid and liquid states. The chemical composition remains unchanged, demonstrating that the identity of the substance is preserved despite the change in its physical state.
What is change in a substance that does not involve a change in the identity?
Then the physical characteristic of a substance change, it is called a change in state. This most commonly occurs when a substance is heated or cooled. The states that substances are solid, liquid and gas. A common example would be water: ice (solid), water (liquid), and steam (gas).
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
What word is used to describe when a substance seems to 'disappear' when mixed with water sometimes colouring it?
The term typically used is "dissolve." When a substance dissolves in water, it appears to disappear as its particles mix uniformly with the water molecules. This is a physical process and does not change the chemical composition of the substance.
Is mothballs disappear over time a chemical change?
It is a Physical Change.
A change in a physical property of another substance is a one physical change chemical change physical property?
It is a change of a physical property - for example the variation of temperature.
The expansion of matter upon heating is an example of what change?
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
How are a chemical and physical change different?
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
Mothballs disappear over time is it a chemical change?
No, mothballs disappearing over time is a physical change, not a chemical change. The mothballs are still the same substance, just dispersed or evaporated into the air.

When a substance from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.

How is a physical change related to a substance physical properties?
a physical change is a change in any physical property of a substance, not in the substance itself
How is a physical change related to a substance physical property?
a physical change is a change in any physical property of a substance, not in the substance itself
Why are metal alloys an example of a physical change and not a chemical change?
They are a physical change because it is not like burning where a new substance is being formed.
