You are a scientist exploring the surface of a new planet. you find a new substance that you do not recognize. as you attempt to identify this substance you notice that it spreads out rapidly to completely fill the container you keep it in. what state of matter is the new substance in? a solid b liquid c gas dplasm

The answer is d plasm

This must be a gas. Gas is the only state of matter that expands to fill its container.

EDIT: Okay, plasma expands as well, but the difference between gas and plasma is that plasma is an ionized form of gas and conducts electricity. Without that information, there's no way to tell.
