Is chlorine gas becoming a liquid a physical or chemical change?
It is a physical change because the chemical composition has not changed.
Is petrified wood a chemical or physical change?
The process of wood becoming petrified involves a combination of both chemical and physical changes. The organic matter in wood is gradually replaced by minerals through a process called permineralization, which is a chemical change. This results in the preservation of the wood's structure, which is a physical change.
Why is butter becoming rancid a chemical change?
Butter becoming rancid is a chemical change because it involves the oxidation of the fats in the butter, leading to the formation of new compounds that give off an unpleasant odor and taste. This process alters the chemical composition of the butter, making it different from its original form.
Is oxygen becoming liquid physical or chemical?
The change of oxygen from a gas to a liquid is a physical change, as the substance itself remains the same chemically. The physical change involves altering the state of the molecules without changing their chemical composition.
How can you be certain that a chemical change has occurred?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
Is bread becoming toast a physical change or a chemical change?
chemical change
Is breath coming as a steam a physical change?
Don't take only my word for it, but, i think it would be a chemical change because if you think about it you are inhaling oxygen and exhaling carbon dioxide. Which would make it a chemical change, but I am not 100% positive.
Is fruit becoming ripe a physical change or a chemical change?
chemical
What do these two changes have in common breath becoming visible on a cold day and stapling an envelope shut?
Both actions involve a change in physical state. In the first scenario, the warm breath is cooled by the cold air, causing it to condense and become visible. In the second scenario, the staple changes the physical state of the envelope by sealing it shut.
Is breath visible on a cold day a change in state?
Yes, the visibility of breath on a cold day is a change in state. When you exhale warm air, it quickly cools down upon contact with the cold air outside, causing the water vapor in your breath to condense into tiny droplets that become visible as mist or fog. This change from invisible water vapor to visible droplets is a physical change in state called condensation.
Is wood becoming charred and black from burning a chemical change?
yes charring of wood is chemical change
Is chlorine gas becoming a liquid a physical or chemical change?
It is a physical change because the chemical composition has not changed.
Why can you see your breath outside in cold weather what phase change is it?
Physical. What's actually visible is not "breath", but rather the moisture in the breath condensing in the colder air. This is a change in physical state from vapor to liquid (in the form of tiny droplets), so it is a physical change.
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.
An example of chemical change?
A tree burning down and becoming ash
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
