1.1- 1.3 Solids Liquids Gases

reverse reaction

reverse reaction

The ________ also happens and is called deposition or desublimation.

Liquids

________ also have a fixed volume but take the shape of the container.

Condensation

________ occurs when a gas changes into a liquid on cooling and it takes place over a range of temperatures.

Solid Changes

Melting is when a(n) ________ into a liquid.

Evaporation

________ occurs only at the surface of liquids where high energy particles can escape from the liquid's surface at low temperatures, below the b.p.

reverse

This is the ________ of melting and occurs at exactly the same temperature as melting, hence the melting point and freezing point of a pure substance are the same.

Zig Zag

The particles follow a(n) ________ path because they are being struck by tiny invisible particles.

Solids

________ have a fixed volume and shape and they have a high density.

Low density

Gases have a very ________.

regular pattern

The particles are packed very closely together in a fixed and ________.

Smells

The ________ are due to tiny particles, which spread because they are by born added by the particles in air, kind of like diffusion.

bubbles of gas

Requires heat which causes ________ to form below the surface of a liquid, allowing for liquid particles to escape from the surface and within the liquid ☄️.

Gaseous Particles

The pressure that a gas creates inside a closed container is produced by the ________ hitting the inside walls of the container.

Thermal energy

When substances are heated, the particles absorb ________ which is converted into kinetic energy.

Kinetic Energy of Particle

Increase in temperature= increase in ________= increase in movement of particles.

Evaporation

________ occurs when a liquid changes into a gas and occurs over a range of temperatures .

Gaseous particles

________ are in constant and random motion.

He saw particles from the pollen jiggling 🤩around, They were not alive

so why were they moving

The color spreads through the water, because the particles leave the solid crystal

it dissolves and spread among the water particles
