Latent heat of fusion = 334 J/g
Latent heat of vaporization = 2260 J/g
What is 2260 kJ?
100
2 L of gas at a pressure of 4 atm occupies this volume at 1 atm
What is 8 L?
200
John Dalton, in 1801, gave us the idea that to find the total pressure of a mixture of gases, you do this mathematical operation involving the partial pressure of each gas in the mixture.
What is add them up?
200
The volume that 2 moles of any ideal gas occupies at 1 atm and 0 degrees Celsius.
What is 44.8 L?
200
Transition from gas to solid
What is deposition?
200
The energy (in J) released when 10.0 g water changes to ice at 0 degrees Celsius
Latent heat of fusion = 334 J/g
Latent heat of vaporization = 2260 J/g
What is -3340 J?
200
A 5 L sample of gas at 100 K occupies 10 L when the temperature changes to this this value
What is 200 K?
300
The law is named after Amedeo Avogadro who, in 1811, hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of these.
What are molecules/moles/particles?
300
The mathematical relationship between temperature and volume
What is directly proportional?
300
Endothermic change of state from the most ordered phase of matter to the least ordered phase.
What is sublimation?
300
The number of kilojoules needed to heat 100. g water from 35 degrees C to 45 degrees C
Cp for water = 4.184 J/(g deg C)

Cp for steam = 2.08 J/(g deg C)
What is 4.2 kJ?
300
Temperature of a 20 atm sample is 200 K. Temperature drops to 50 K and pressure changes to this value.
What is 5 atm?
400
This is the only quantity that decreases as pressure increases for a given sample of gas when temperature is kept constant.
