Semantics
2 weeks
What is the name of the term that describes how hard it is to heat something up?
specific heat
What tool/ model do we use to model storage and transfer of energy?
Bar Charts
What phrase or word has Ms. Poole written the most on the gas law tests?
TEMP MUST BE IN KELVIN!
What are the 3 temperature scales we have discussed in this class?
Fahrenheit, celsius, and kelvin
Predict: Which assessment was the most reassessed test this semester?
Combined Gas laws (the last one)
What is the name for the effect of particles colliding with a 2 dimensional surface?
Pressure <3
What is the relationship between mass and volume called?
Density
How many gas laws did we learn? Bonus points if you can give the names for all!
4: Charles', Boyle's, Gay Lussac's, "Hagan's"
What is Celsius temperature scale based on?
Freezing and boiling points of water
What class periods does Ms. Poole have available for relearning?
2nd and 9th period
(it's the same next semester too!)
Who created the Kelvin temperature scale?
Lord Kelvin
What is the term for what happens to any substance when it is cooled and the volume decreases?
Thermal Contraction
In an experiment students doubled the Kelvin temperature of a substance while they increased the volume of the container it was in by 2x. What effect would this have on pressure?
Pressure would stay the same, if volume and temperature both double, the particles will have twice as much energy but also twice as much space to move around.
How many degrees Celsius are in 1 degree of Kelvin?
1
They are the same degree size but start at different points
What is Ms. Poole's favorite animal?
Prairie Dog
What is temperature?
The average kinetic energy of the particles
What was the Fahrenheit temperature scale based on?
0 was the freezing point of a brine solution of salt and water. Also aligned well with human body temperature when the freezing point of water (32) was multiplied by 3 to get 96
What was the most common day of the week to have a chemistry assessment this semester?
Fridays (3)
Followed by 2 on Tuesday and 1 on Wednesday
Name 5 pressure units (EXTRA 200 points to name the atmospheric pressure values for all of them)
101.3 Kpa, 1 atm, 14.70 PSI, 760 mmHg, 760 Torr, 101,325 Pascals
Why is it inappropriate to say "degrees Kelvin"?
Because Kelvin is an absolute temperature scale, "degrees" means that it is in reference to something else.
How many degrees Fahrenheit are in 1 degree Celsius?
1.8, from the slope of the line of F v. C
