State of Matter
Which of the three states of matter have a definite volume and variable shape?
Liquid
What is the definition of Pressure?
force distributed over an area. Force / Area
What state of matter does melting start and end up as?
Solid to Liquid
If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?
1.29L
What are three states of matter?
Solid Liquid and Gas
Which state of matter takes the shape and volume of the container it is in?
Gas
What are the three factors that effect the pressure a gas exerts?
Temperature, Volume, and the number of particles
What are the two vaporization processes?
Evaporation and Boiling
A bag of potato chips is packaged at sea level (1.00 atm) and has a volume of 315 mL. If this bag of chips is transported to Denver (0.775 atm), what will the new volume of the bag be?
406ml
What is the formula for the combined gas law?
P1V1 = P2V2
T1 T2
Which of the states of matter have the strongest attractions between its atoms?
Solids
What kind of relationship do temperature and pressure have?
Direct relationship means if one goes up so does the other and vice versa
What is an example of Condensation
Water on the outside of a cold glass
A commercial airliner has an internal pressure of 1.00 atm and temperature of 25° C at takeoff. If the temperature of the airliner drops to 17° C during the flight, what is the new cabin pressure?
0.97atm
What happens to the temperature of matter goes through a phase change?
It stays the same, it does not change until the complete phase change.
The atoms of which state of matter move the fastest?
Gases
What relationship do volume and pressure have?
Indirect relationship, if one goes up the other goes down and vice versa.
What is sublimation?
solid to gas
A Los Angeles class nuclear submarine has an internal volume of eleven million liters at a pressure of 1.250 atm. If a crewman were to open one of the hatches to the outside ocean while it was underwater (pressure = 15.75 atm), what be would the new volume of the air inside the submarine?
873,000L
List the order of attraction between atom from strongest to weakest
What are the 2 other states of matter?
Plasma and Bose-Einstein condensate (BEC)
What relationship do the number of particles and pressure have?
Direct relationship means if one goes up so does the other and vice versa
Which phase change is gas to solid?
Deposition
A small research submarine with a volume of 1.2 x 105 L has an internal pressure of 1.0 atm and an internal temperature of 15° C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 3° C, what will the volume of the gas inside be if the hull of the submarine breaks?
767 L
What are the three parts of the Kinetic Theory of Gases?
1.Particles in a gas are in constant, random motion.
2.The motion of one particle is unaffected by the motion of other particles unless the particles collide.
3.Almost no attraction between particles.
