Is hollow block a physical change?
No, hollow block is not a physical change. A physical change refers to changes in the state or appearance of a substance without altering its chemical composition. However, hollow block is a building material made from a mixture of cement, sand, and other aggregates, which undergoes a chemical change (hydration) during the curing process.
Is Sanding a block if wood a physical chemical or nuclear change?
Sanding a block of wood is a physical change. This process involves the mechanical removal of material from the surface of the wood, altering its texture and appearance without changing its chemical composition. The wood remains wood, and its chemical properties are unaffected by the sanding.
Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
Is changing a block of metal into a thin wire a physical change?
Yes. The wire and the block are still composed of the same material - only the shape has changed.
Why is the tearing paper a physical change not a chemical change?
Tearing a piece of paper in half means a physical change because nothing happens to the paper, it's still paper although, if you set it on fire, that would be a chemical change because it is now changed into a different element. hope this helps d^^b

Does a melting block of ice experience a chemical of physical change?
It is a physical change: change of state of matter from solid to liquid.
Is a block of ice changing from a solid to a liquid a physical change?
Yes, the process of a block of ice changing from a solid to a liquid is a physical change because the chemical composition of water remains the same during this transition. The change in state from solid to liquid is reversible.

Is a blue block physical or a chemical property?
physical
Is blue block a physical property or chemical property?
physical
Why does physical change differ from a chemical change?
As a basic example: When a block of ice melts into water, the change is physical (solid to liquid) yet the chemical contents of the ice/water remains unchanged. If a lot of salt is then dissolved in the melted water, it is still water, yet it has changed chemically into a saline (salty) solution. The added salt will increase the water's density - which could be a physical change!
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
