Nature of Matter

TermDefinition
Matter word used to cover all substances and materials from which the universe is composed.
Fluids describes liquids and gases since they flow easily due to their particle arrangement.
compressible meaning the volume can be reduced by an application of pressure
kinetic movement
melting point the temperature when a solid turns into a liquid due to the increase in energy
evaporation when particles escape from the liquid surface to the surrounding atmosphere and become a vapour
volatile a liquid which evaporates easily and has low boiling points
boiling point the fixed temperature when a vapour pressure of the liquid is equal to the atmospheric pressure, and hence the liquid will boil.
reflux when evaporation and condensation take place a number of times simultaneously
melting the change when a solid is heated and changes to a liquid
freezing the change when a liquid is cooled to a solid
condensation the change of the vapour or gas into a liquid when cooled. This takes place over a range of temperatures
boiling the temperature at which a pure liquid changes into a gas is the boiling point.
sublimation when substances change from a solid directly into a gas when heated, without passing through the liquid stage and vice versa
examples of gases that sublime iodine, ammonium chloride and dry ice
diffusion the way particles in the substance spread out to occupy all the space available to them, from a region of high concentration to a region of low concentration
density the mass of particles in a solid, liquid or gas for a given volume of that solid, liquid or gas.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
