Combined Gas laws
When using gas law formulas, what unit must temperature always be converted to?
Kelvin (k)
60cm to mm
600mm
Is the breaking of chemical bonds an endothermic or exothermic process?
Endothermic; it requires energy to break them
What are the three things needed for combustion to occur
Fuel, Oxygen, and Heat/Spark
119
If the pressure of a gas is doubled and the temperature is kept the same, what happens to the volume?
The volume gets cut in half
2000 lb to tons
1 ton
Which type of strong chemical bond involves the sharing of electrons between atoms?
Covalent
In a 4-stroke engine, what is the name of the first stroke that pulls the fuel-air mixture into the cylinder?
Intake Stroke
Are we allowed to talk while Ms.Cassidy is talking?
NO
A gas has a volume of $10 L at $300 K. If the pressure stays the same and the temperature is doubled to $600 K, what is the new volume?
20 L
5.2 km to m
5200
What is the name of the high-energy molecule (hydrocarbon) typically used as fuel in a combustion engine?
Octane or Gasoline
What do you need for compression to work in an engine?
Spark plug
True or False
Logan shops at Brandy Melville
TRUE
State the equation for the Combined Gas Law.
P1V1/T1=P2V2/T2
16.5 km to m
16500m
When fuel burns in an engine, chemical energy is converted into what two other types of energy?
Thermal/Heat and Mechanical/Kinetic energy
What part of the engine provides the "heat" or "spark" necessary to ignite the fuel-air mixture?
Spark Plug
How often do we do a blooket in class
Everyday
A container holds $2 L of gas at a pressure of $1 ATM and a temperature of $100 K. If you double the pressure to $2 atm and double the temperature to $200 K, what is the new volume?
2 L
8,920 m to km
8.92 km
Explain how the molecular expansion of gases after a chemical reaction creates "work" in a piston.
The reaction releases heat, increasing gas pressure which forces the piston down
During the "Exhaust" stroke, what is the primary gas being pushed out of the engine?
Carbon Dioxide and Water Vapor
