Gas Vocab
Gas Law that describes how the pressure of a gas increases as the volume of the container decreases.
Boyles Law
Vaporization at the surface of a liquid that is not boiling
Evaporation
(Boyle's) The volume of a gas is 250 mL at 340 kPa pressure. What will the volume be when the pressure is reduced to 50 kPa?
1700 mL
How many moles are contained in 78.4 L of Neon at STP?
3.5 mol
What process occurs as a solid becomes a liquid?
Gas Law that describes how gases expand when heated
Charles' Law
The process of particles absorbing heat energy to change to a gas
Vaporization
(Charles') A ballon filled with helium has a volume of 30 L at 15 Degrees C. What will be the volume of the balloon if the temperature is increased to 80 degrees C?
36.77L
What is the volume of 0.8 moles of chlorine gas at STP?
17.92 L
What process occurs as a gas goes to a liquid?
condensation
Gas Law that describes how the Pressure of a gas is directly proportional to its kelvin temperature.
Gay-Lussac's Law
The temperature at which a liquid changes to a gas
Boiling point
(Gay Lussac) A rigid container of O2 has a pressure of 340 kPa at a temperature of 713 K. What is the pressure at 273 K?
130.18 kPa
How many molecules are contained in 16.8 L of Xe at STP?
4.52 x 1023 molecules
What process occurs as a liquid goes to a solid?
freezing
Equal Volumes of different gases held at the same temperature and pressure must contain the same number of particles
Avogadro's Principle
the temperature at which a solid changes to a liquid
melting point
(Gay-Lussac) The pressure of a gas in a tank is 3.2 atm at 22 degrees C. If the temperature rises to 60 degrees C, what will be the gas pressure in the tank?
3.61 atm
How many moles are contained in 39 L of Fluorine gas at STP?
1.74 moles
What process is occurring if you are moving from a gas to a solid directly?
deposition
The name of the condition where pressure is equal to 1 atm and temperature is equal to 1 degree Celsius.
STP
The change of a solid directly to a gas
Sublimation
(Combined) A gas at 110 kPa and 30 degrees C fills a container with an initial volume of 2 L. If the temperature is raised to 80 degrees C and the pressure to 400 kPa, what is the new volume?
0.64 L
If a 1 mole sample of oxygen gas is at STP, what will its volume be?
22.4 L
Why doesn't the temperature increase in a substance that in in the process of a phase change?
The added energy is being used to overcome the intermolecular forces in the molecule.
