What is the relationship between heat and kinetic energy?
Heat is how we measure kinetic energy in atoms
Heat measures how fast your spinning hard drive can spin
More heat = more kinetic energy
Atoms in a cold substance have little kinetic energy

What is the equation for specific heat?
Q = m∆t
Q = C∆t
Q = mC∆t
Q = m1
Q = mC∆t
Which letter means which?
Q = heat energy
m = temperature increase in celsius
c = mass
t = specific heat
Q = specific heat
m = mass
c = celsius (temperature increase)
t = heat energy
Q = heat energy
m = mass
c = specific heat
t = temperature increase in celsius
Q = Queen Elizabeth
m = motherboard version
c = CPU cores
t = TPM version
(0 for none)

What is thermal energy?
Energy in a thermos
the energy contained within a system that is responsible for its temperature
Heat
What is heat?
Flow of thermal energy
Measure of thermal energy
Measure of kinetic energy in atoms
Flow of kinetic energy in atoms
Describe temperature.
A unit for measuring heat/kinetic energy/thermal energy
Determines the speed of molecules (slow = cold, fast = hot)
There are three units of temperature: Celsius (Cº), Fahrenheit (Fº), and Kelvin (K)
All of the above
Describe the kinetic molecular theory.
Particles of matter are always moving
Volume of one particle is 0
When particles hit or presses on the container walls, it exerts pressure
Particles do not exert forces on each other
What is the relationship between states of matter and thermal energy ("energy")?
There is no relationship
Gas = low energy
Liquid = high energy
Solid = medium energy
Solid = low energy
Liquid = medium energy
Gas = high energy
Solid = high energy
Gas = medium energy
Liquid = low energy
Describe how gases behave under certain conditions.
When gas is under pressure, the density increases because the molecules are bunched tightly
When gas is heated, the molecules go into speed mode and expand because the molecules move faster
none of the above

What is the difference between fission and fusion?
Fission can be done on Earth in nuclear power plants, but fusion can only be done in the Sun as of 2021.
Fission generates radioactive waste as a by-product, while fusion usually only generates harmless helium as a by-product
Fission is when atoms are split to create energy, while fusion is when atoms are fused together to create energy
They are mostly the same process
