Air Pressure is the effect of
collisions of air molecules against surfaces
Pressure in gases is a measure of:
the number of collisions per second of the particles with the side of the container.
the force of the collisions of the particles with the side of the container.
the amount of space taken up by the particles in the container.
None of the above
Pressure can be exerted by solids, liquids and gases.
TRUE
FALSE
The pressure inside the balloon will:
Decrease
Increase
Remain the same
Not enough information to formulate an answer
The pressure of the gas in the balloon in the ice water will be:
Greater than that of the balloon in the boiling water.
Less than that of the balloon in the boiling water.
The same as that of the balloon in the boiling water.
Not enough information to answer the statement.
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?
The pressure will increase
The pressure will decrease
The pressure will remain constant
The pressure will equalize
We can increase the pressure of a gas by:
Adding more gas.
Reduce the volume of the container.
Increase the temperature of the gas.

Wht will happen when heat is added?
Particles will increase speed
Pressure will increase
The chamber will expand
The number of molecules will increase
What will happen when the system is cooled?
The molecules will slow down
the temperature will decrease
the pressure will decrease
the lid might blow off
What is happening in this diagram
liquid water is vaporizing due to heat
air molecules are being pushed out of the can
the metal is getting warmer
the water vapor is condensing into liquid
What is happening to the can in this picture
the partial vacuum inside the can is pushing against the sides
the air and water pressure outside is pushing on the sides of the can
the water is being sucked up into the can
Which best explains why the sphere will not go through the ring after it is heated?
The particles in the sphere moved faster when heated.
The particles in the sphere slowed down when heated.
The particles in the sphere got closer when heated.
The particles in the sphere spread out when heated.
What happens to molecules when the temperature drops or lowers?
The molecules get closer together
The molecules start moving faster.
The molecules stop moving.
The molecules become smaller.
You watch your science teacher put a balloon in a bowl of liquid nitrogen and see the balloon has shrunk like a raisin. Which answer BEST explains how you know if HEAT ENERGY been ADDED or REMOVED.
HEAT ENERGY has been ADDED. I know this because the balloon has become LARGER meaning the molecule ARRANGEMENT is FARTHER APART.
HEAT ENERGY has been REMOVED. I know this because the balloon has become SMALLER meaning the molecule ARRANGEMENT is CLOSER.
HEAT ENERGY has actually stayed the SAME. I know this because the balloon has NOT CHANGED meaning the molecule ARRANGEMENT is also NOT CHANGED.
Water went up the test tube after heating, steaming and then turning over into the bowl of water because...
it wanted to go up
the water in the bowl was cooler than the air in the tube
the pressure in the tube was less than the pressure outside the tube
the water was sucked into the tube
The balloon inflated on the heated flask because....
the pressure inside the balloon was less than outside
the air molecules inside the flask were being heated and their volume was expanding
the air was cooler outside the flask so we made the air pressure outside less
because it wanted to inflate
The balloon on the flask stopped inflating because....
it wanted to stop inflating
the forces were in equilibrium
the flask started to cool
the pressure outside was greater than the pressure inside
How does heat energy reach the Earth from the Sun
Convection
Radiation
Conduction
Insulation
What is the definition of CONDUCTION?
When heat is transferred from objects like rays of light or electromagnetically.
a hot liquid or air that expands, becomes less dense, and rises or becomes more dense, and sinks.
When thermal energy transfers by collisions between particles.
When heat transfers through the heater or AC in your house.
What is the definition of CONVECTION
When heat transfers through waves.
When heat transfers from objects that are touching.
The transfer of thermal energy in a fluid (liquid/gas) by movement of warm / cool fluids.
Heat traveling from the sun
True or False: When water begins to boil air bubbles form in the liquid.
