Is molded clay physical or chemical change?
physical, because it can be easily reversed
Is clay being molded into new shape a physical shape?
Yes, molding clay into a new shape is a physical change. This process involves altering the form of the clay without changing its chemical composition. Once the clay is reshaped, it retains its original properties, making it a reversible physical change.
Why is erasing a pencil mark a physical or chemical change?
PHYSICAL
What are some examples of chemical and physical changes that a kid can do?
A kid can observe a chemical change by mixing vinegar and baking soda to create fizzing and bubbling from the release of carbon dioxide gas. A physical change can be demonstrated by melting crayons to create new shapes without altering their chemical composition.
Clay pot fired in a kiln physical or chemical?
The firing of a clay pot in a kiln involves both physical and chemical processes. The physical process is the application of heat to the clay, causing it to harden and form a solid structure. The chemical process involves the transformation of the clay minerals into a more stable crystalline structure through processes like dehydration and recrystallization.
What type of change does modeling clay through in a person's hand?
Clay undergoes a physical change when it's in someone's hands.
Is a rolling a ball of clay into a long strand a chemical change?
No, rolling a ball of clay into a long strand is a physical change, not a chemical change. The clay's composition remains the same; only its shape is altered.
Is mixing water with clay a chemical change?
Mixing water with clay is not a chemical change, as no new substances are formed. It is a physical change, where the clay particles are dispersed in the water but retain their original chemical composition.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
When you press a clay is it physical or chemical change?
Well, honey, when you press clay, you're just applying physical force to change its shape, so that's a physical change. No need to bring any fancy chemicals into the mix for this one. Just get your hands dirty and mold that clay however you please!
Why is making a figure from lump of clay considered a physical change?
Making a figure from a lump of clay involves physically shaping and molding the clay without changing its chemical composition. This is a physical change because no new substances are formed during the process, and the clay can still be returned to its original state by reshaping it.
Is clay is molded into a new shape a physical or chemical change?
This demonstrates a physical change. The way the clay looks is now physically different because the shape of it has changed.
Is clay being molded into new shape a physical shape?
Yes, molding clay into a new shape is a physical change. This process involves altering the form of the clay without changing its chemical composition. Once the clay is reshaped, it retains its original properties, making it a reversible physical change.

Is molding clay a physical change?
It is a physical change, because you are only changing the shape of the clay and all of the chemical properties stay the same. Also, the molding of the clay is reversible. An example of physical change would be a melting popsicle because the substance is changing from a solid to a liquid and keeps all of it's properties. The substance doesn't change, only the shape/form.
