a. particles that make up a substance move b. bonds between atoms break down c. molecule of gas rush together d. lighter particles within a substance clump together
a. particles that make up a substance move
All changes of the state of matter require a (n) ________ change.
a. water b. vibration c. energy d. sublimation
c. energy
The metric unit of pressure is _______.
a. Newton b. Meters squared c. psi d. Pascal
d. Pascal
What type of change occurs when water changes from a solid to a liquid?
a. chemical change b. physical change c. irreversible change d. freezing
b. physical change
Which of the following phase changes in “Endothermic”?
a. condensation b. vaporization c. deposition d. freezing
d. freezing
The motion of one particle of a gas is unaffected by the motion of other particles of the gas unless the particles _________.
collide
During vaporization, a substance changes from a (n) _______ to a __________.
“Liquid” to a “Gas”
A (n) __________ has a definite volume and a definite shape.
“Solid”
Evaporation occurs ________ the boiling point of the substance.
“At or Below”
Materials can be classified as solids, liquids, or gases based on whether their shapes and ________ are definite or able to change.
“Volume”
The kinetic theory states that the particles in matter are always in __________.
“Motion”
As gas molecules bounce around and collide, they spread to _____.
“fill all available space”
When water _________ , energy is released.
freezes
For any change of state to occur, ________ must be transferred.
Energy
Ice cubes left in the freezer for several months will become smaller because of _________.
Sublimation
You go into a coffee shop and thee whole place is filled with the pungent smell of freshly brewed coffee. Explain what is happening in terms of the Kinetic Theory of matter…
The atoms of the pungent smelling coffee bounces around the shop.
Compare and contrast the phase changes of sublimation and deposition ( Tell how they are the same and different)
“Sublimation”– changing from a solid to a gas w/o passing through liquid. “Deposition” – changing from gas to a solid w/o passing through liquid. **They are opposites, but both do not pass through the liquid phase.
What happens to the air pressure in tires on a hot day after a long road trip? Explain
The air pressure in the tire goes up because friction causes the temperature to increase. As temperature rises, pressure increases.
Boyle’s Law can be written as P1V1 = P2V2. Explain what v1 and v2 represent.
v = volume; v1 represents volume of a gas before a change occurs, v2 represents the volume of a gas after a change occurs.
List the 5 states of matter in order if increasing energy. Circle the state of matter that is the most commonly found in the universe?
f
