4. you bought a block of cheddar from the grocery store. if you cut a small piece and a large piece from the same block of cheese, will they have the same density?

They will have same density

Explanation:

Density is defined as the mass contained per unit volume.

Density is characteristic of a compound and thus remains constant at fixed temperatures.

A small piece would have lesser amount and will occupy a smaller volume. Similarly a larger piece would have larger amount and will occupy a larger volume.

Thus the ratio of mass and volume will remain fixed or constant and the density will be same for smaller and larger piece.

d) physical means can be used to separate the components of air.
