Solids, Liquids & Gases

QuestionAnswer
States of matter solid, liquid, gas and plasma are the four states of matter
Kinetic theory of matter tiny, particles in constant motion
Crystal in most solids the particles are arranged in repeating geometric patterns
Plasma is a gas-like mixture of positively and negatively charged particles
Thermal expansion almost all matter expands as it gets hotter and contracts when it cools
Polluted water refers to water that contains such high levels of unwanted materials that it is unacceptable for drinking or other purposes
Thermal pollution excess heat in the water
Evaporation a liquid changes to a gas gradually at temperature below the boiling point
Condensation takes place when a gas changes to a liquid
Heat of fusion the amount of energy needed to change a material from the solid state to a liquid state
Heat of vaporization the amount of energy needed to change a material to a liquid and then to a gas
Pressure is the amount of force exerted per unit of area
Boyle’s Law if you decrease the volume of a container of gas the pressure of the gas will increase
Charles’ Law the volume of gas increases with an increase in temperature
Buoyant force the upward force on an object immersed in it
Archimedes’ Principle the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object
Pascals’ Principle pressure applied to a fluid is transmitted unchanged throughout the fluid
Bernoulli’s Principle as the velocity of a fluid increases, the pressure exerted by the fluid decreases

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.
