What is the Kinetic Molecular Theory of Gas?

• The idea that of motion in between molecules

• That gas particles exhibit perfect inelasticity

• That gas particles are in constant motion and exhibit perfectly elastic collisions

• That gas particles are stationary

What is an assumption of the kinetic theory of gases?

• Not a perfect temperature

• There is no force of attraction between molecules

• There is a force of attraction between molecules

• They have a volume

How do molecules create pressure?

• As they collide with the walls they impart momentum producing a force perpendicular to the wall

• They constantly move in random directions that end up creating pressure

• Cop out answer

• By decreasing the temperature resulting in less movement

What is absolute temperature?

• Temperature measured from boiling point of water

• A temperature measured from the freezing point of water

• A temperature measured from absolute zeros in kelvin

• A temperature measured from the average temperature of the earth

What does STP stand for?

• Obligatory cop out answer

• Standard Temperature Power

• Standard Thermal Process

• Standard Temperature and Pressure

What factors affect gas policies?

• The temperature of the gas

• The pressure of the gas

• The volume of the gas

• The number of molecules in the gas

How is atmosphere pressure related to boiling?

• The higher the pressure the faster the liquid will evaporate

• The greater the pressure the more energy required for liquids to boil

• The lower the pressure the more energy required

• The greater the pressure the faster the liquids cool off

Another factor that affects pressure

• The depth

• The humidity

• The altitude

• The volume

What is Boyle's Law?

• The pressure and volume of a gas have an inverse relationship

• The temperature and volume of a gas have an inverse relationship

• The temperature and pressure have an inverse relationship

• Pressure and temperature have a direct relationship

What is Charle's Law?

• A law that is inversely proportional to pressure

• A law that states pressure is inversely proportional to volume

• An experimental gas law that describes how gases tend to expand when heated

• A law that states the volume is directly related to the pressure
