Intro to Energy #1
What are the fire triangle components?
Energy doesn't have..
Mass or volume.
The energy of an object's movement.
What is a Endothermic reaction doing?
Adsorbing heat, along with creating a cooling effect.
It expands.
The fuel for a wildfire could be, what?
Wind, oxygen, burning trees, dried grass, etc.
What does some Potential Energy transform into?
It could transform into heat.
What is Potential Energy?
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
What is a Exothermic reaction doing?
Releasing energy, warms up.
What does lightning produce when it strikes something?
It produces Ozone.
If you were to pour water on a flame, what would happen?
It would cool the fire down. This'll cause for it to go out.
What's Heat Flow?
The rate of which heat flows rates for all energy transformations.
What is Energy?
Energy could be a lot of things. Such as the capacity to move, do work, change matter, or produce heat.
What are Molecules held together by?
Chemical bonds.
What are graphite and diamond mostly composed of?
Carbon.
What is a Joule?
The Sl unit of energy
What is Gasoline?
Stored Chemical Potential Energy.
What is Thermal Energy?
Energy in some system that's responsible for it's temperature, a form of Kinetic Energy.
What reaction would cause for Chemical Potential Energy to convert into Kenetic Energy?
An Exothermic reaction.
One inch of rain is equal to how many inches of snow?
13 inches of snow.
One calorie is equal to how many Joules?
4.148J
The only reason you can detect energy, is because..
Of what it does.
What is Chemical Potential Energy?
How does Activation Energy affect the rate of a Chemical Reaction?
As the activation energy increases, the rate of reaction decreases.
It needs to be -196°C at atmospheric pressure.
