Chapter 7 Gas laws and attractive forces

TermDefinition
At the constant temperature and constant moles, the volume of gas is inversely proportion to> the pressure. This is which law? Boyle's law
pressure, and temperature of gas at constant volume and constant moles are direct propositional
London dispersion forces attractions between molecules depends on what two factors? Molar mass and shape
Oils are generally at room temperature and are obtained from liquids; plants
What type of lipid is predominantly found in cell membranes? phospholipids
A molecule that contains both polar and nonpolar regions is described as Amphipathic
The transition from the solid phase directly to the gas phase is called sublimation
What is the pressure of nitrogen in atmospheres of a sample that is at 745 mmHg? 0.980 atm
If a scuba diver's lungs have a normal capacity of 49Lat sea level (1.0 atm), what would be the volume of her lungs if the pressure at a depth of 50 ft is 975 mmHg? 3.8 L
A balloon originally had a volume of 4.39 Lat 44°C and a pressure of 729 torr. To what temperature must the balloon be cooled to reduce its volume to 3.78 L if the pressure is constant? 0.0 C
compare two compounds of similar molar mass in which A is comprised of nonpolar molecules and 8 composed of polar molecules. Which will boil at a high temperature? B will boil at a higher temperature than A will.
______attractions are the only ones that all molecules have regardless of what they are composed of. London dispersion forces
The long hydrocarbon tails of soap molecules are: hydrophobic and repeal water

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.
