Tallest in the class.
Who is Slater?
The number of meters in exactly one kilometer.
What is 1,000 meters?
This term describes a reaction that absorbs energy from its surroundings, making the test tube feel cold.
What is Endothermic?
These are the three "ingredients" required for the Fire Triangle: Fuel, Heat, and this gas.
What is Oxygen?
If you squeeze a balloon (decreasing volume), the pressure inside does this.
What is Increases?
Ms. Cassidy's major.
What is chemistry?
This is the standard unit of energy used in chemistry, abbreviated as "J."
What is the Joule?
Energy is always ______ when a chemical bond is broken.
What is Absorbed (or Required)?
Combustion reactions are always this type of "thermic," because they release heat to the environment.
What is Exothermic?
This variable must be held constant for the Combined Gas Law to work.
What is the Amount of Gas (or Moles/n)?
The height of Ms. Cassidy.
What is 5'2?
To convert a temperature from Celsius to Kelvin, you must add this number.
What is 273?
This is the term for the average amount of energy needed to break a specific type of bond in one mole of a substance.
What is Bond Energy?
This black, powdery substance is often produced during incomplete combustion.
What is Soot (or Carbon)?
If a gas at 300 K has its temperature doubled to 600 K (at constant volume), the pressure will change by this factor.
What is Double?
The amount of teeth Pine has lost.
What is one tooth?
This prefix means 10^{-2}, or one-hundredth, commonly used for measurements on a ruler.
What is centi-?
When calculating triangle H using bond energies, you use the formula: Bonds ______ minus Bonds ______.
What is Broken minus Formed?
This is the name for the specific amount of heat energy required to raise the temperature of 1 gram of a substance by 1°C.
What is Specific Heat Capacity?
This is the volume of a gas if 2.0 L at 100 K is heated to 200 K at constant pressure.
What is 4.0 Liters
The amount of posters in the room
What is 35?
If a gas has a pressure of 2.0atm, this is its pressure in kilopascals (kPa).
What is 202.6 kPa?
A carbon-carbon triple bond is ______ and ______ than a carbon-carbon single bond.
What is Stronger and Shorter?
On a potential energy diagram, this represents the difference between the energy of the reactants and the peak of the "hill."
What is Activation Energy?
This is the pressure of a gas if its original 1 ATM, 1L, 100 K state is changed to a 2 L volume at 200 K.
What is 1 atm?
