Properties of Matter

They tested magnetism without changing the material (there were no chemical reactions).  That means that magnetism is a _______ property.

• physical

• chemical

The sodium reacted with the water (explosively!).  REACTIVITY changed the materials.  It is a _______ property.

• physical

• chemical

They checked the density of these materials without changing them.  Therefore, DENSITY is a _______ property.

• physical

• chemical

The acetone changed the styrofoam in a reaction.  So REACTIVITY is a _______ property.

• physical

• chemical

The slime didn't change when they put it in water.  So DENSITY is a ________ property.

Why do you think the sulfur hexafluoride isn't escaping from the fish tank?  There is no lid on the tank.

• Sulfur hexafluoride is denser than air so it sank to the bottom of the fish tank.

• They didn't use very much sulfur hexafluoride.

• It takes at least 15 minutes for it to rise high enough to get out of the tank.

Why is a plastic handle a good choice for the pan?

• It's smoother to hold on to when stirring food in the pan.

• It doesn't conduct heat like metal does.

Some properties of matter are magnetism, solubility, and density.

• True

• False
