When a can is crushed, the volume decreases due to the change in shape. The material inside the can gets compacted, reducing the amount of space it occupies. The actual change in volume depends on the extent of the crushing.
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
this queston is stupid
Yes, a crushed can has chemical properties. They are the same as those of the can before crushing. Crushing a can is a physical reaction and not a chemical one. For instance, if a soup can is made of steel, the steel can be chemically attacked by something like sulfuric acid. And this is true whether the can is crushed or not.
The change in volume of an object due to temperature change is given by the coefficient of volume expansion (α), which for aluminum is about 0.000023 per degree Celsius. Given the initial temperature change from 0 to 100 degrees Celsius, the total change in volume can be calculated using the formula: ΔV = V * α * ΔT, where V is the initial volume, α is the coefficient of volume expansion, and ΔT is the change in temperature. Substituting the values, you can find the change in volume of the aluminum sphere.
no its got the same amount of density therefore its mass if the same.
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. While the volume of the can decreases when it is crushed, the mass of the metal remains constant. Therefore, the density, which is mass divided by volume, remains unchanged.
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.
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.
it is a physical change :-)
Of course. Like anything, when bread is crushed, its density increases. Anything that is crushed will have higher density in its crushed state. The only things that you can crush and NOT (permamently) increase their density are those that return to their original shape after being crushed. The increase in density is due to the fact that there is more bread in a smaller volume. When you squeeze the bread, you squeeze out some of the air, reducing its volume while maintaining its mass. Density = mass/volume.
The density of the metal in the crushed can remains the same as the density of the metal before it was crushed. Density is an intrinsic property of a material that does not change with physical alterations like crushing. So, the density of the metal in the can will not change due to the crushing process.
Some of the physical quantities that change the most when a junked car is crushed into a compact cube include volume, density, and structural stability. The volume of the car decreases significantly as it is crushed, leading to a much higher density in the compact cube. The structural integrity of the car is also altered, with the transformation from a complex shape to a simple cube impacting its stability and strength.
Percentage change in volume= Change in volume/intial volume X 100
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
It is only a physical change.
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
