Which best describes the physical change of an aluminum soda can after its crushed?
A change in the mass of can
B change in weight of can
C change of volume of can
D change in the specific heat of can
C = change in the volume of the can. Everything else remains the same. Specific heat is a chemical property, not a physical one.

C) change of volume of can
The best answer choice that describes the physical change of an aluminum soda can after it's crushed is C) Change of volume of can.
To understand why option C is the correct answer, let's break down the other options:
A) Change in the mass of the can: When a can is crushed, the amount of aluminum in the can doesn't change. The mass of the can remains the same since no aluminum is lost. Crushing the can only rearranges the same mass of aluminum into a different shape, so the mass doesn't change.
B) Change in weight of the can: Weight is the force experienced by an object due to gravity. Crushing an aluminum can does not change the force of gravity acting on it, so the weight remains the same.
D) Change in the specific heat of the can: Specific heat refers to the amount of heat energy required to raise the temperature of a substance. However, crushing a can does not affect its specific heat since this property depends on the material itself, not its shape or size.
Therefore, the best answer is C) Change of volume of the can. When an aluminum soda can is crushed, its volume decreases. The can is compressed or flattened, reducing its overall size and volume while maintaining the same mass and weight.
