Phy SCI 9 Unit 2 Matter and Gas Laws 24-25

What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?

• There will be no change

• I will move those 2 students in 6th period group 3 further apart

• The volume will increase

• The volume will decrease

How will the behavior of the gases in the piston chamber change if more pressure is applied to

the piston?

• There will be no change

• The gas particles will hit the

  walls less frequently

• The gas particles will hit the walls

  more frequently

• The gas particles will become more solid with more pressure

Pushing down on the piston causes an increase in pressure and a decrease in the volume of the gas in the chamber. Why?

• The gas particles have both

  positive and negative charges

• There is a large relative distance between gas particles

• Gas particles are usually tightly

  packed together

• Gas particles have definite

  shape and volume

A cap on a 2 Liter Bottle of Mountain Dew must remain tightly on the bottle or else it will go flat. Why?

• The cap prevents the liquid in the

  Mountain Dew from evaporating

• The cap allows extra oxygen

  inside the bottle to

  increase freshness and fizz

• The cap allows CO2 to escape

  easily keeping the soda fresh

  and ready

• The cap keeps pressure

  constant preventing CO2 from

  escaping

If we double the pressure on a sample of gas (at constant temperature), what happens to the volume of the gas?

• None of the above

• The volume remains the same

• The volume is halved

• The volume is doubled

A gas is being condensed to a liquid. Which of these arrangements of particles looks most like a LIQUID?

• A

• B

• C

• D

Taylor took an inflated balloon outside on a very cold day. The balloon began to shrink. Why?

• Gas particles became warmer,

  gaining energy, speeding up,

  increasing pressure inside the

  balloon

• Gas particles became cooler,

  losing energy, slowing down,

  decreasing pressure inside the

  balloon

• Taylor bought a cheap, poorly

  made balloon.

• Taylor should have stayed inside reading Mr. Goss' warm-ups by

  the fire.
