Question

The three different states of matter are liquid, solid, and gas. A solid is something you can hold in your fingers, while a liquid is something you can hold in a cup. Gases are all around you, making up the air we all breathe. These three states are very different. However, liquids and gases do have some things in common. One of these is A) that liquids and gases are both less dense than solids. B) that liquids and gases are both more dense than solids. C) that liquids and gases both take the shape of their container. D) that liquids and gases do not take the shape of their container. Eliminate

Answer 1

A) Liquids and gases are both less dense than solids*.

*Except for the very special case of water.  Ice is less dense than liquid water.  That's why cubes float in soda, and bergs float in the ocean.

Answer 2

The answer is C. that liquids and gases both take the shape of their container.  

Think of it this way, if you take an ice cube and put it in your glass, it will stay in its shape and stay that way until it melts.  But if you put liquid or a gas into a glass, it will take the shape of the glass that it is put into.
