When chalk is crushed is it a physical or chemical property?
Crushing chalk is a physical change, not a chemical change. Physical changes alter the form or appearance of a substance without changing its chemical composition. So, when chalk is crushed, it remains the same substance chemically but in a smaller form.
Is a pop can being crushed a physical change?
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
When aluminum is bent are the molecules crushed?
No, for two reasons.First is that bending is a physical change, and physical changes do not affect chemical composition. It is not possible to 'crush' a molecule; the only way to break it apart is by way of a chemical or nuclear reaction.More importantly, however, aluminum is a basic chemical element. As such, in its pure state it doesn't have molecules as such; instead, it is composed of interlinked aluminum atoms held together by what's known as metallic bonding.
What are 3 chemical properties of a crushed can?
Aluminum can react with the oxygen in air to form aluminum oxide, which gives the can a dull, oxidized appearance. Crushing the can may result in changes in the surface area of the aluminum, potentially affecting its reactivity with other substances. The aluminum in the crushed can can still undergo chemical reactions with acids or bases if they come into contact with the can's surface.
Is a crushed can a physical change?
yes it is physical change but how can it be rewanable thats my question
When an aluminum can is crushed did it undergo a physical change or a chemical change?
When a aluminum can is crushed, it undergoes a physical change, because even though the object got crushed and misshaped it still has the same identity.The identity has never changed.
How does the density of the metal in the crushed can compare with the metal's density before the can was crushed?
It depends on what you're measuring: the density of the aluminum or the aluminum and the space inside the can. If it's the density of the aluminum only, it doesn't change much. If it's the density of the aluminum and the space inside the can, the density greatly decreases as you are getting rid of the air, and therefore the volume, inside. This also depends on if you are using your foot or a garbage compacter.

Does a crushed can weigh less than one not crushed?
No, a crushed can does not weigh less than an uncrushed can – the weight of the aluminum remains the same regardless of its shape. The can may appear smaller due to being crushed, but the weight remains constant.

What are the physical changes that occur during the recycling of aluminium cans?
magnets are used to pull out any accidental iron or steel cans in the mixthe cans are crushed together to form an aluminum baleseveral bales are placed in a crucible and meltedmelted aluminum is poured into a mold and solidified into an ingotthe ingot is rolled or extruded to form the desired shapeif cans are desired rolled sheet aluminum is stamped to form the bases and lids
How much does a 55 gal drum weigh of crushed aluminum cans?
On average, a 55 gallon drum filled with crushed aluminum cans can weigh around 300-400 pounds. The weight can vary depending on factors such as the density of the crushed cans and the specific type of aluminum being recycled.
When a solid is crushed to a powder physical change?
When a solid is crushed to a powder, it undergoes a physical change because its composition remains the same, but its form and size are altered. This process increases the surface area of the material, which can affect its physical properties, such as solubility and reactivity. Unlike chemical changes, no new substances are formed during this process.
Does an aluminum can weigh the same after you crush it?
yes. because you didn't add anything to it or take anything away from it. so it's just a different size.
