Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
No shape, no fixed volume — just fill.
A gas has no fixed shape and no fixed volume. Its particles are far apart and move freely, so a gas expands to fill whatever container it is placed in.
↳ Weak forces + free, fast particles = a gas fills any container completely.
Four numbers describe any gas.
↳ P, V, T, and n are the four variables that fully describe a gas sample.
Tiny fast particles explain everything.
The kinetic molecular theory explains gas behaviour by treating a gas as a large number of tiny particles in constant random motion.
↳ Gas pressure comes from countless particle collisions with the container walls.
Gases are the state of matter with no fixed shape or volume, whose particles move freely and fill any container. Their behaviour is described by measurable properties such as pressure, volume, temperature, and amount, an...

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which statement best describes a gas?
BeginnerIt has neither a fixed shape nor a fixed volume.
A gas has neither a fixed shape nor a fixed volume because its particles are far apart and move freely, spreading out to fill any container.
Gas pressure on the walls of a container is caused by which of the following?
BeginnerCollisions of gas particles with the walls
Pressure is the total force per unit area from countless gas particles colliding with the container walls.
Why are gases much more compressible than solids and liquids?
BeginnerGas particles have large empty space between them.
The large interparticle space in gases allows particles to be pushed closer together under pressure, making gases highly compressible.
Temperature of a gas is a measure of which quantity?
BeginnerThe average kinetic energy of the particles
Temperature measures the average kinetic energy of gas particles — the hotter the gas, the faster the particles move.
