Matter exists in three main states, solid, liquid, and gas. Solids have a definite shape and volume (for example Ice). Liquids, likewater, have a defined volume but can change their shape depending upon the container. Everyone needs one or more of the three states of matter in some way....
A. made up of particles packed closely together, having both definite shape and definite volume. B. made up of particles packed relatively close together, having an indefinite shape but a definite volume. C. Which state of matter has a definite volume and takes the ...
gas, in physics, one of the three commonly recognized states of matter, the other two being solid and liquid. A substance in the gaseous state has neither definite shape nor definite volume. Like liquids, gases are fluids and assume the shape of their containers. Unlike liquids, they will ...
A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charg...
Gas is a state of matter characterized by its molecules or atoms being arranged without structure so that they are collectively fluid and have neither a definite shape nor a definite volume. A basic gas definition in chemistry or physics is that gas is one of the three fundamental states of ...
Think about it… Why does a solid have a definite shape and a definite volume? Water Water exists on our planet in three states. Ice, water, and water vapor What causes water to be in one phase or another? ENERGY When energy is added to a substance that energy causes the particles in...

If one could observe a gas under a powerful microscope, one would see a collection of particles (molecules, atoms, ions, electrons, etc.) without any definite shape or volume that are in more or less random motion. These neutral gas particles only change direction when they collide with anot...

Gases (substances that exist in a gaseous state) have no definite shapes and no fixed volumes. Gaseous substances are highly compressible and occupy the shape of their container. Q13. Gases cannot be liquefied unless their temperature is brought down to or below their critical temperature. Justify...
