GASES

chapter 5 gases chemistry

TermDefinition
What is the perspectives studied in the chapter 5 gases? Microscopic (studying the concept of molecules) and Macroscopic (focuses on the large scale property)
Pressure the sum of molecule collisions on the surface
Pressure Formula P=F/A
how do we measure gas pressure? by balancing a liquid pressure (due to gravity)
Hydrostatic pressure Formula P=ghd
What is the barometer? PHg = Patm a tube closed at one end filled with Hg and inverted in the pool of Hg and the weight of Hg causes level in the tube to drop
What is a nanometer? is appaturus structure used to measure gas pressure
common unit for pressure N/m²= kg/ms²=Pa
properties of gases gases are easy to compress and expand gases have much lower density compared to liquid or solids gases expand to fill a container gases are more far apart gases are in constant motion gases move faster due to kinetic energy at high temperatures
Maxwell Boltzmann distribution to determine the distribution of the kinetic energy of for a set of molecules
Manometer Formula Pgas=Patm + ΔP
What standard units of pressure? 1atm and 1bar

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.
