RMS 6 matter

rms 6th grade science

TermDefinition
matter anything that has mass and takes up space
solid matter with a definite shape and volume; it has loosely packed particles that vibrate
liquid matter with definite volume, but no definite shape; it has medium packed particles that move at medium speed
gas matter with no definite volume or shape; it has particles that move quickly in all directions
plasma a state of matter that only exists at extremely high temperatures; it is not common on Earth, but it is common on stars
viscosity a liquid's resistance to flow
surface tension the uneven forces acting on the particles on the surface of a liquid
energy the ability to do work or cause change
kinetic energy the energy of motion or energy that is being used
potential energy the energy of position or stored energy
thermal energy the total kinetic energy of all the particles in a sample of matter
temperature the average kinetic energy of the individual particles in a sample of matter
heat the movement of thermal energy from a substance of higher energy to a substance of lower energy
melting the process of changing from the solid state to the liquid state due to the absorption of thermal energy
freezing the process of changing from the liquid state to the solid state due to the lost of thermal energy
vaporization the process of changing from a liquid to a gas state due to the absorption of thermal energy
condensation the process of changing from a gas to a liquid due to the absorption of thermal energy
force a push or pull
pressure the force exerted on a surface divided by the total area over which the force is exerted; pressure = force/area
buoyant force the upward force exerted on an object immersed in a fluid
Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object
density the mass of an object divided by its volume; density = mass/volume
Pascal's Principle states that when a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid

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.
