Molding a piece of silver using heat is a physical change. This is because it is changing shape and not chemically changing the silver.
When you cut a piece of cloth, the property that changes is its physical form or structure. The cloth transitions from a single piece to multiple pieces, altering its dimensions and shape. However, the material properties, such as composition and texture, remain the same. This illustrates a physical change rather than a chemical one.
The density of each piece remains the same as that of the original brick of pure silver. This is because density is defined as mass per unit volume, and since the mass and volume of each piece are both reduced proportionally, the density does not change. Thus, each piece maintains the same density as the original brick.
The 40% proof silver set was a 3 piece.
The crown is Europe's stamp for silver. It simply means that the piece was made in Europe. European jewelry may also have a lion stamp. Is it possible that this piece is actually silver and not gold? If so, the 36 means that the piece contains 36% silver.
The number 328 on a piece of silver jewelry typically indicates the purity of the silver. Specifically, it suggests that the item is made of 92.8% silver, which is commonly known as sterling silver. The remaining percentage usually consists of other metals, like copper, which enhance the silver's durability. Always verify with a jeweler, as markings can vary by manufacturer.

Crushing a piece of chalk is only a physical change. Chemically, it is still chalk.

Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.

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.
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
no it is not a physical change because folding a piece of paper does not chemicaly change it.
