Physical Ch 3: BL

Beaver Local 3

QuestionAnswer
What theory states that atoms and molecules move FASTER as the temperature INCREASES? Kinetic Theory of Matter
What theory states that: at the same temperature more massive particles move SLOWER than massive ones? Kinetic Theory of Matter
How is the state or physical form of a substance partly determined? By how the substance particles move
by determining whether the shape and volume are definite or variable, you can classifymatter into these three states. liquid, solid, gas.
what state of matter have a definite shape and volume? solid
the state of matter that changes shape but not volume is called what? liquid
this state of matter changes both shape and volume. gas
these two states of matter are also known as fluids. liquids and gases
the most common state of matter that does not have a definite shape or volume. plasma
these are found in lightning, fire and the arora borealis. natural plasmas
the ability to change or move matter or to do work. energy
because particles are in motion, they have this kinetic energy
a measure of the average kinetic energyof the particles in an object temperature
the total kinetic energy of a substances atoms thatdepends on particle speed and number of particles thermal energy
what does not change during the change of state? the identity of a substance
what does change during the change of the state? the energy of a substance
some changes of state require this. energy
the change of a sustance from a liquid to gas evaporation
the process that changes solids directly into gas sublimination
the temperature at which a liquid boils boiling point
the temperature at which a substance changes from solid to liquid, which also depends on pressure melting point
the change of state from a gas to liquid condensation
the temperature at which a liquid changes into a solid freezing point
the temperature at which gas becomes a liquid condensation point
this is constant during the change of state temperature
these two things cannot be created or destroyed in the fundamental laws of physical science mass or energy
the law where mass cannot be created or destroyed law of conservation of mass
the law where energy cannot be created or destroyed law of conservation of energy
the amount of force exerted per unit area of a surface pressure
the SI unit for pressure and is equal to the the fforce of 1N exerted over an area of 1 m^2 pascal
the upward force that keeps an object immersed in or floating on a liquid boyant force
all of these exert an upward boyant force on matter fluids
the princilple that says that the boyant force on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces Archimedes' principle
the principle that states that a change in pressure at any point in an enclosed fluid will will be transmitted equally to all parts of the fluid Pascals' principle
how fast do fluids move through small areas compared to large areas faster
the resistance of a gas or liquid to flow vicosity
the princilple that states that as moving fluid increases, the pressure of the moving fluid decreases Bernoullis' principle
this state of matter expands to fill its container and have low densities gas
the laws that state the mathematical relationships between the volume temperature, pressure,and quantity of gas gas laws
the law that says when pressure increases, volume decreases and visa versa Boyles' law
the law that states that the pressure of gas increases as the temperature increases, if the volume of the gas does not change and the pressure decreases as the temperature decreases. Gay Lussac's law
the law that says; for a fixed amount of gas at a constant pressure, the volume of the gas increases as the gas's temperature increases. likewise, the volume of the gas decreases as the gas's temperature decreases Charle'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.
