Terms in this set (34)
matter having a definite shape and volume
matter that has a definite volume but take the shape of their container
matter that does not have a definite volume or shape
a nonsolid state of matter in which the atoms or molecules are free to move past each other, as in a gas or liquid
a state of matter that consists of free-moving ions and electrons
the ability to do work
a measure of the amount of heat in mater; a measure of the average kinetic energy of the particles in an object
the total kinetic energy of a substance's atoms; depends upon the number of particles in the substance
a change in state from liquid to gas
a change in state from a gas to a liquid
a change in state from a liquid to a solid
a change in state from a solid directly to a gas
the temperature at which a substance changes from solid to liquid
the temperature at which a liquid boils
the temperature at which a gas becomes a liquid
the temperature at which a liquid becomes a solid
the amount of force exerted per unit area of a surface
the SI unit of pressure: equal to the force of 1N (Newton) exerted over an area of 1m2
the upward force that keeps an object immersed in or floating on a fluid
the resistance of a gas or liquid to flow
the laws that state the mathematical relationships between the volume, temperature, pressure, and quantity of a gas
(For a fixed amount of gas at a constant temperature.) If the pressure of a gas decreases, the volume of the gas increases. Likewise if the volume of the gas increases, the pressure of the gas decreases.
The pressure of a gas increases as the temperature increases, if the volume of the gas does not change. The pressure decreases as the temperature decreases.
(For a fixed amount of gas at a constant pressure.) The volume of the gas increases as the gases temperature increases. Likewise the volume of the gas decreases as the temperature decreases.
Kinetic Molecular Theory
the theory that all matter is composed of particles (atoms and molecules) moving constantly in random directions
States of Matter
solid, liquid, gas
Conservation of Mass and Energy
Mass and energy are both conserved. Neither mass nor energy can be created or destroyed.
Fluid pressure is always directed
The three common states of matter are
solid, liquid, gas
What happens as the temperature of a gas in a balloon increases?
The volume of the gas increases
An iceberg is partially submerged in the ocean. At what part of the iceberg is the water pressure the greatest?
At the lowest depth
Why are liquids instead of gases used in hydraulic brakes?
Liquids cannot be compressed easily. Gases are easily compressible.
Will a ship loaded with plastic-foam balls float higher or lower in the water than an empty ship?
Lower. The foam balls will add to the mass/density of the ship causing it to sink a little.
Use Boyle's law to explain why bubbled packing wrap pops when you squeeze it.
As the bubble is squeezed to a smaller volume, the pressure of the gas inside the bubble increases until it is high enough to burst the bubble.
