States of Matter
Name the three states of matter
Solid, Liquid, Gas
Name the three factors that affect gas pressure.
Temperature
Volume
Number of Particles
A balloon, at 37 K, has a volume of 581 L. You left for a while and
when you came back, the balloons volume is now 637 L. What
temperature is the balloon?
40.57 K
Define Exothermic and Endothermic
Exothermic: Energy is released
Endothermic: Energy is absorbed
In solids, describe (or draw) how atoms are arranged
Very close to each other, low energy, arranged in an orderly way
For solids, are the shape and volume definite or indefinite?
Shape: Definite
Volume: Definite
If Volume increases, what happens to pressure?
Pressure Decreases
A gas sample expands to a final volume of 79.0 L where it exerts a final
pressure of 35.0 atm. If its original volume was 46.0 L before the
expansion, what was its initial pressure?
60.11 atm
When I go from a solid to a liquid, what state change is that? Is it Endothermic or Exothermic?
Melting
Endothermic
What is the word that is defined as 'A result of a force over an area'
Pressure
For Liquids, are the shape and volume definite or indefinite?
Shape: Indefinite
Volume: Definite
When the temperature goes down, what happens to the pressure?
Pressure decreases
A gas occupies 87 L at a pressure of 7.00 atm. What will its
new volume be if the pressure increases to 9.50 atm?
64.11 L
When I go from a gas to a liquid, what state change is that? Is it Endothermic or Exothermic?
Condensation
Exothermic
This word is defined as: the amount of heat an object needs to melt
Heat of Fusion
For Gases, are the shape and volume definite or indefinite?
Shape: Indefinite
Volume: Indefinite
Did Charles' Law find that temperature and volume are directly or inversely proportional?
Directly Proportional
A sample of gas has a volume of 76.00 L at a pressure of 11.50 atm and a temperature of 460 K. If the pressure is increased to 33.00 atm and the temperature is raised to 853 K, what is the new volume of the gas?
49.11 L
There are two different types of vaporization (liquid to gas), what are they?
Boiling and Evaporation
What unit does temperature NEED to be in during gas law calculations
Kelvin
What are the other two states of matter (NOT solid, liquid, or gas)
Plasma
Bose-Einstein Constant
Did Boyle's Law find that pressure and volume are directly or inversely proportional?
Inversely proportional
10.94 Pa
When I go from a gas to a solid, what state change is that? Is it Endothermic or Exothermic?
Deposition
Exothermic
Name 5 state changes
Melting
Boiling
Freezing
Condensation
Sublimation
Deposition
