Changing state is a physical change. The chemical composition of the substance doesn't change, only the form the substance takes. Liquid water changing to ice is still water-- the chemical composition hasn't changed.
An example of chemical change would be methane (CH3) burning in oxygen (O2) to form carbon dioxide (CO2) and water vapor (H2O). The methane and oxygen no longer exist as themselves but have become carbon dioxide and water vapor-- their chemical compositions have changed.
What else can I help you with?
Are there observable similarities between physical and chemical change?
Well obviously, a physical change and a chemical change both envolve changing of state
Is heat changing water to steam a chemical or physical change?
The process of heat changing water to steam is a physical change. During this transformation, water molecules gain energy and move from a liquid state to a gaseous state, but their chemical composition remains the same (H₂O). In a physical change, the substance alters its form or state without changing its chemical identity.
Is condesing a chemical change?
No, it is a physical change because there is no change in chemical composition of the substance that is condensing.
Is State chemical or physical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
Is concrete setting a physical or chemical change?
It would be both. It's a physical change because it is changing state and a chemical change because water is being evaporated.
Is changing from a gas to a liquid a chemical change?
No, changes of state such as this are physical changes.
Is a chemical change a liquid becoming a gas?
No, a liquid changing to a gas is a change of state or a physical change.
Is liquid becoming a gas a chemical change?
No, a liquid changing to a gas is a change of state or a physical change.
Is sweat evaporating from your forehead a chemical change?
No, sweat evaporating from your forehead is a physical change, not a chemical change. The sweat is merely changing from a liquid state to a gas state without any change in its chemical composition.
Is the change of state a physical?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
Is a physical change a change of state?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
Is scrubbing the floor a physical or chemical change?
Scrubbing the floor is a physical change because the appearance or state of the floor is altered without changing the chemical composition of the materials involved.
