States of Matter
The 3 states of matter found in nature
Solid, liquid, and gas
The volume of 1 mole of gas at STP
22.4 L
The temperature at which a liquid turns into a gas
Boiling point
The molarity of a solution which contains 2 moles of solute in 4 liters of solution.
0.5M
A solution in which water is the solvent
Aqueous solution
The state of matter with particles that is compressible
gas
Standard temperature and pressure
0 degrees C and 1 atm
The reason water is a good solvent
It is polar
A rigid container of O2 has a pressure of 388 kPa at a temperature of 713 K. What is the pressure at 273 K?
149 kPa
the conversion of a liquid to a gas or vapor at a temperature below the boiling point
evaporation
A measure of the average kinetic energy of a substance
Temperature
This increases when the pressure on a gas increases.
temperature
The attractions between adjacent water molecules
Hydrogen bonds
What is the % (m/m) of a solution containing 25 g of NaCl in 175 g of solution?
14%
Mixtures containing particles that are intermediate in size between those of suspension and true solutions
colloid
Changes in this cause changes in state
The amount of kinetic energy in the substance
The difference between a real gas and an ideal gas
volume and intermolecular forces
The inward force that tends to minimize the surface area of a liquid
Surface tension
A gas has a volume of 3.5 m3 when the temperature is 27 degrees C and the pressure is 115 kPa. What is the volume of the gas if the temperature drops to -10 degrees C and the pressure drops to 99 kPa?
3.6 m3
Describes a solution that contains more solute that can theoretically be held at a given temperature
supersaturated
The key difference between the 3 states of matter
The three assumptions of the kinetic theory of gases
A measure of the force exerted by a gas above a liquid of the same type
vapor pressure
A gaseous product of a reaction is collected in a 25.0 L container at 27 degrees C. The pressure in the container is 216 kPa, and the gas has a mass of 96.0 g. What is the molar mass of the gas? (R = 8.31)
44.2 g/mol
The escape of a gas through a tiny hole in the container of gas
