How the three states of matter fill a container?

(c) Gaseous O2 fills its container completely—regardless of the container’s size or shape—and consists of widely separated molecules. The state of a given substance depends strongly on conditions….1.1: The Phases of Matter.

Temperature	State	Density (g/cm3)
0°C–100°C	liquid (water)	0.9997 (at 4.0°C)
≥100°C	vapor (steam)	0.005476 (at 127°C)

What state of matter is inside the balloon?

Gases in Balloons Balloons aren’t technically gases. They are little pieces of rubber. However, the helium (He) inside the balloon is a gas. Helium is a noble gas that has a very low atomic mass.

What state of matter is smoke?

Smoke is a fine solid formed by incomplete burning. Fumes are fine airborne particles produced when a solid vapourises and condenses, eg during welding.

Which state of matter is invisible?

Students have particular problems with recognising the existence of gases as a physical state of matter because most gases are invisible.

What is the smallest possible unit of matter called?

atom
atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry. Atomic model of electron configurations.

Is air matter Yes or no?

But, like solids and liquids, air is matter. It has weight (more than we might imagine), it takes up space, and it is composed of particles too small and too spread apart to see. Air, a mixture of gases, shares properties with water vapor, the gaseous form of water that is part of air.

Can we see air Yes or no?

Air is transparent to our eyes because we have evolved retinas that are sensitive to the very wavelengths of light that pass through it unobstructed – otherwise we wouldn’t be able to see anything at all.
