Compare the density of a gas to the density of solids and liquids.
Gases are less dense than both solids and liquids.
100
The KMT is based on the fact that gases are in _______.
Constant Random Motion
100
It is caused by gas molecules collisions against the walls of its container.
What is gas pressure?
100
What is the relationship between temperature and volume? Whose law is this?
Charles' Law
Temperature is directly proportional to volume. As one increases, so does the other.
100
What are the parameters that affect gases?
Pressure, temperature, and volume.
200
The volume and and shape of a gas is ____.
Indefinite or insignificant
200
Gases moving from high to low concentration.
What is Diffusion?
200
Removing molecules from a container _______ pressure.
Decreases
200
What is the relationship between pressure and volume? Whose law is this?
Boyle's Law
Pressure is inversely related to volume. As pressure increases, volume decreases.
200
Without changing the temperature or volume of a gas, how can you increase the pressure?
The pressure will increases with the amount of gas molecules present due to an increase in collisions.
300
Convert 0.83 atm to kilo pascals.
84.1 kPa
300
Gases escaping through a small hole from areas of high concentration to areas of low concentration.
What is effusion?
300
List the units of pressure and their values.
1 atm. 760 mmHg. 101.3kPa.
300
Whose gas law led to the creation of a new temperature system known as the Kelvin Scale?
Charles' Law.
300
Discuss the relationship between Kinetic and Energy and Temperature.
Temperature is directly proportional to Kinetic Energy. Therefore, if you increase temperature you will increase the Kinetic Energy.
400
Explain why gases are easily compressed.
Gases are composed mostly of empty space.
400
Collisions of gas molecules where the kinetic energy of the molecules is conserved.
What is elastic collision?
400
Atmospheric pressure ______ climbing a mountain.
Decreases.
400
A 5L balloon is at a pressure of 1.5 atm. If the pressure decreases to 1 atm what is the new volume of the balloon?
It will increase to 7.5 L.
400
If 2 variables are inversely proportional what happens to the second variable when the first is tripled?
The second variable will be 1/3 of its original value?
500
Which gas will diffuse more quickly from a container ammonia (NH3) or hydrogen (H2)? Why?
Hydrogen will diffuse more quickly due to its lighter mass.
500
Temperature is a measure of ______.
Average Kinetic Energy of gas molecules.
500
What are the standard pressure and temperature conditions?
0 degrees Celsius and 1 atm
500
A 5L balloon at 300K is cooled slightly to 273K, what is the new volume?
4.55L
500
If at 25 C the volume of a container at 101.5 kPa expands from 2.50 L to 5.0 L, what is the final pressure of the container? Report your answer in mmHg.
