General Science RT

General science review for the RT program at Pima Medical

QuestionAnswer
Boiling Point The temp. at which vapor pressure exceeds atmospheric pressure
Latent Heat of Vaporization the energy required to vaporize a liquid

humidity water vapor pressure
AH Absolute Humidity
RH Relative Humidity
%BH Body Humidity
The temp at which condensation happens. dew point
high temps increase evaporation and vise versa influence of pressure

standard temp and pressure dry STPD
STPD (usually) 22.4
the ratio of the mass of a substance density
process where molecules moves from high concentrated areas to low concentrated areas. Diffusion
gas diffusion rates Graham's Law
relationship between partial pressure in a gas mixture Dalton's Law
predicts how much of a given gas will dissolve in a liquid Henry's Law

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.
