Yes it is a physical change not a chemical change.
p.s. an example of a chemical change is an apple roting

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.
What are five signs of a chemical reaction?
-Colour -Temperature -Light -Gas produced (Bubbles) -Precipitate -Hard to reverse Examples: Cooking an egg: This is a chemical reaction for several reasons. As you cook an egg the temperature increases, also the colour of the whites change, and it is very hard to reverse. Melting a block of ice: This would not be a chemical change because it is rather known as a Physical Change. A physical change includes signs as decrease in size or change in state. In this situation the block of ice is going from a solid, to a liquid.
Science what do you use for heating small amounts of liquid?
Generally you'd use a heat block.
How do you use bung in a sentence?
a bung is something U use to block the liquid so it doesn't fall out!!!!!:)
What family or group does element mercury belongs to?
Hg is in the 12th group. It is a d block metal. It is a liquid in state.
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 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.
Is hollow block a physical change or a chemical change?
the hollow block is a chemical change
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.
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!
Changing from a 350 small block to a big block 454 in a 1978 Chevy 4x4 would you need to change the motor mounts?
no
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).
When the block was placed in the liquid why did the liquid rise?
The matter of the block displaced the water causing the water to rise
Do they change IP addresses on wikis while anon only?
Nope. If they block anonymous users only, changing ip address will be restricted.
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
Is a blue block physical or a chemical property?
physical
Is sublimation melting or freezing?
SUBLIMATION: It is a process in which a solid instead of changing into liquid state changes directly into gaseous state upon heating. MELTING: It is a process in which a solid at its melting point changes into liquid state upon heating.
