# properties of a gas

TermDefinition
A gas A gas is defined as a substance that has no well defined boundaries but diffuses rapidly to fill the container in which it is placed
Kelvin Scale Temperature can be converted into the kelvin scale by adding 273 to the celsius
1 kPa 1000 pa
1 litre 1000 cm
Standard temperature and pressure 273K & 1x10(5) Pa
Boyles Law States that, at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure
Charles' Law States that, at constant pressure the volume of a fixed mass of gas is directly proportional to to its temperature measured on the Kelvin Scale
Combined gas law equation P1_V1 = P2_V2 T1 T2
Reaction between gases The volumes of the reacting gases are in the ratio of small whole numbers provided the volumes are measured at the same temperature and pressure
Avogadro's Law States that equal volumes of gases contain equal numbers of molecules, under the same conditions of temperature and pressure
Ideal gases Gases that obey all the assumptions of the kinetic theory of gases under all conditions of temperature and pressure
Real Gases They differ from ideal gases because 1) Forces of attraction and repulsion between molecules and 2) the volume of the molecules is not negligible
The equation of state for an ideal gas PV=nRT
convert Volume in cubic metres - volume in litres litres X 10(-3)
Convert cubic metres to cm cm X 10(-6)

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
