How do crystalline solids differ from amorphous solids?
crystalline solids - particles form a regular, repeating pattern.
amorphous - becomes softer & softer or change into other substances.
_________ law describes the relationship between a gas's temperature and volume when its pressure is constant.
Charles's
When a substance cools, it loses __________ energy to its surroundings
thermal
which state matter undergoes changes in volume most easily?
gas
DAILY DOUBLE
in cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best explains this event is
sublimation
At constant temperature, when the volume of a gas is decreased, what happens to its pressure.
it increases
Molecules on the surface will escape into the air -- change of state from liquid to gas - evaporation.
How do you convert Celsius to Kelvin?
+273
Pieces of dry ice (solid carbon dioxide) become smaller through the process of
sublimation
The surface of water can act like a sort of skin due to a property of liquids called
surface tension
DAILY DOUBLE
Pressure can be measured in units of
A. newtons
B. newtons per square meter
C. newtons per centimeter
D. newtons per cubic centimeter
Newtons per square meter
How do the motion of particles differ in gases, liquids, and solids?
solids - fixed position, vibrating
liquid - moving slowly, fill containergas - moving sporadicly, many collisions
An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall above the back of the stove. What sequence can you infer has occurred?
DAILY DOUBLE
What is Guy-Lussac's equation.
P1/T1=P2/T2
STP - pressures are
_______ kPa
______ atm

The pressure of 6.0 L of a gas is 200 kPa. What will be the volume if the pressure is doubled, keeping the temperature constant?
P1V1=P2V2
V2 = 3 L
DAILY DOUBLE
A balloon at constant temperature has a volume of 2.0 L at 3 atm. If the pressure is reduced to 0.5 atm, what would be the volume of the balloon?
P1V1=P2V2
V2 = 12L
DAILY DOUBLE
A container holds 50.0 mL of nitrogen at 25 degrees celsius and a pressure of 736 mmHg. What will be its volume if the temperature increases by 35 degrees celsius. (converts to kelvin)
V2 = 55.87 mL
DAILY DOUBLE
Convert 0.875 atm to mmHg.
multiply the atm value by 760.0 mmHg / atm.
0.875 atm/1 x 760 mmHg/1 atm = 665 mmHg
A 600 mL sample of nitrogen at constant pressure is heated from 300 K to 350 K. What is the final volume?
V1/T1=V2/T2
700 mL
