Thermal Energy, Temperature and its readings
The total kinetic and potential energies of its particles
What is thermal energy?
The sun heating up the Earth.
What is radiation?
E=Q-W
What is the 1st law of Thermodynamics equation?
This is a non-renewable resource.
What is a fossil fuel?
The objects have the same temperature.
What is thermal equilibrium?
Heat is transferred from the hand to the ice cube.
Why does an ice cube melt?
What is solar energy?
Some mass is converted into energy in a nuclear reaction.
What is E=mc2?
Fossil fuels power the machine that shakes the tree so that the apples fall to the ground.
What is using FF *gas* to harvest apples?
The object's particles move faster.
What is when temperature increases?
The object's particles move slower.
What is thermal energy decreases?
The ice absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a solid to a liquid.
What is ice melts?
Quickly moving neutrons coming out of the reaction are slowed down by water. The water heats up and turns into steam. The steam turns the turbine and produces electricity.
What is how does a nuclear power plant produce energy?
Nuclear energy produces much more energy than burning fossil fuels.
What is a disadvantage of using fossil fuels?
The average kinetic energy of their particles is the same.
What is they have the same temperature?
273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
What is these are the same temperatures?
The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
What is water turns from liquid to a gas (steam)?
Some of uranium's mass is converted into energy, so the smaller atoms have less mass.
What is fission?
using crayons to color
What is an indirect use of fossil fuels?
As the temperature increases, the kinetic energy of the molecules increases.
What is the relationship between temperature and KE?
373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit
What is these are the same temperatures?
Only plants use solar energy in a chemical process to produce food.
What are why are plants the beginning of a food chain?
The control rods absorb excess neutrons, keeping them from causing too many uranium atoms to split too quickly.
What is keeping a nuclear reaction safe?
Nuclear energy is very expensive.
What is an advantage of using fossil fuels?
The objects' temperatures have both changed by the same amount.
What is NOT part of thermal equilibrium?
