Question

A substance is tested in a lab. It is found to maintain a unique shape and is a good conductor of electricity. If it is made up of electrons, protons, and neutrons, what state of matter is this substance most likely to be? gas liquid plasma solid

Answer 1

Answer is: solid.

There are five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).

In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container.

Liquids have definite volume, but no fixed shape.

Gases (for example nitrogen and neeon) not have definite volume and fixed shape, it depends on its container.

Plasma is a an ionised gas with highly electrical conductivity.

Answer 2

The answer is solid.
