Is Toothpaste A Solid Liquid Or Gas. Toothpaste is a colloid, because it's part solid and part liquid. Toothpaste is made up of small solid material that is spread into the fluid.
Toothpaste is neither a solid, gas nor liquid. Keeping this in view, what state of matter is elephant toothpaste? As the oxygen is continually made the foam squeezes out of the bottle like toothpaste for an elephant!
