Physical and Chemical Properties of Matter

Maple syrup is

• an element

• a compound

• a homogeneous mixture (solution)

• a heterogeneous mixture

You have a 2 g iron cube and a 4 g iron cube. After looking at the density, magnetism, and conductivity of each, what should be the MOST likely findings?

• 4g cube was better at everything because it was bigger

• 4 g cube was more magnetic because it was bigger. Everything else was the same.

• 2 g cube was lower at everything because the matter was squeezed into a smaller space.

• The cubes were equal. The amount of matter would not change these properties.
