Is molding of plastic into toys a chemical change?
no its just physical change
What is an example of a physical rather thena chemical change?
Carving a stone or molding a dough
Is molding of iron into iron pipes a physical or a chemical change?
It is a physical change, because a section of pipe would react the same chemically as the original iron would. You can crush or melt the pipe back into the formless mass of iron that you started with.
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.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Cheese molding chemical or physical change?
Cheese molding is a chemical change because the microorganisms present in the environment break down the proteins and fats in the cheese, leading to the formation of new compounds. This process cannot be reversed, unlike physical changes where the structure or state of a substance can be changed without altering its chemical composition.
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.
What is are some examples of a physical change?
Melting of ice, boiling of water, tearing a piece of paper, and breaking a glass are all examples of physical changes. These changes do not alter the chemical composition of the substances involved, they only involve a change in their physical appearance or state.
Is molding jewelry physical or chemical?
Molding jewelry is primarily a physical process. It involves shaping materials, such as metal or resin, into desired forms using molds without altering their chemical composition. While some processes, like casting, may involve chemical changes (e.g., melting and solidifying), the act of molding itself is focused on the physical manipulation of materials.
Is the melting point of silver a physical or a chemical property?
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
