Science Test 3

QuestionAnswer
What are the three points of the "kinetic theory"? 1. matter is made up of atoms and molecules 2. the atoms and molecules act like little tiny particles that are always in motion 3. When the temperature is increased, the particles move faster
at the same temperature, more massive particles move ----- than less massive ones ( slower;faster) slower
Describe the shape and volume of a SOLID : definite shape; definite volume
Describe the shape and volume of a LIQUID takes shape of container; definite volume
Describe the shape and volume of a GAS : takes shape of SEALED container(freely escape in open space); volume of container
a nonsolid state of matter in which the atoms or molecules are free to move past each other, as in a gas or liquid is a ---- Fluid
The most common state of matter --- Plasma
a state of matter that consists of free-moving ions and electrons Plasma
all particles of matter have --- kinetic energy
the ability to do work --- energy
measure of average kinetic energy --- temperature
thermal energy depends on --- speed and amount of particles
total kinetic energy of a substances atoms is ---- thermal energy
thermal increases as temperature ---- increases
volume increases - pressure decreases Boyle's Law
pressure increases - temperature increases Gay - Lussac's Law
volume increase - temperature increases Charles's Law
speed of moving fluid increases - pressure decreases Bernoulli's Principle
pressure is equally exerted Pascals Principle
buoyant force = upward force = weight of fluid the object displaced Archimedes Principle

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.
