Is separation of 2 liquids by distillation a physical change?
Yes, separation of two liquids by distillation is a physical change. It involves the process of heating a mixture of liquids to vaporize one of the components, and then condensing the vapor back into a liquid form. This process does not involve any chemical reactions or changes in the chemical composition of the substances.
When 2 colorless liquids mixed togather to form a bright yellow solid what physical properties have changed?
The change in color from colorless liquids to a bright yellow solid indicates a change in the substance's optical properties. Additionally, the change in physical state from liquid to solid indicates a change in the substance's state of matter and possibly its intermolecular forces.
What is most likely sign that a chemical change has happened?
Two liquids are mixed at room temperature and a gas forms.
Is mixing sand and gravel a physical or chemical change?
It's a physical change
What kind of change took place in the bottle a chemical change or a physical change?
To determine whether a change in a bottle is a chemical or physical change, consider the nature of the change. A physical change involves alterations in appearance or state without changing the substance's chemical composition, such as freezing or melting. In contrast, a chemical change results in the formation of new substances through reactions, such as rusting or combustion. If the bottle's contents are simply mixed or heated without new substances forming, it's a physical change; if new substances are produced, it's a chemical change.
When you mix 2 liquids and it is warm to touch is it a chemical or physical change?
Can be both or either. 1. When mixed, without chemical reaction, liquids can take or release heat; it is a physical phenomenon. 2. But mixed liquids can react and this chemical reaction can also release heat.

This is a physical process.
Is sugar mixed with food coloring a physical change?
Mixing is a physical process.
Is mixing two substances and light is produced a chemical or physical change?
If light is produced when two substances are mixed, it is most likely a chemical change. Chemical changes involve the formation of new substances with different properties, whereas physical changes typically only affect the state or appearance of a substance without altering its chemical composition.
