2 types of energy resources
renewable and nonreneable resources
1. Heat always transfer from a (n)______ object to a(n)_______ object.
Hotter to colder
Heat transfer by electromagnetic waves moving away from the hot object in all directions.
ONLY transfer that can happen through matter OR a vacuum (space!)
Radiation
Type of energy is energy stored between bonds in chemical compounds.
Chemical energy
Examples:
Food (and digestion)
Fuel/Gasoline
Batteries
The higher an object is, the more ________________ energy it will contain.
Potential energy
A resource that can be replaced in a relatively short amount of time. Produce very little waste products so they are clean for the environment
renewable energy
2. Heat will continue to move from the hotter object to the colder object until they are the same temperature.
Thermal equilibrium
Examples of each
Conduction, Radition and Covection
Type of energy is energy from the flow of electrons.
Electrical energy
Examples:
Basically anything that has a plug or uses wires
Cable and ethernet lines
Things operated BY batteries (not the battery itself which is chemical energy)
Examples of (moving car, speeding car, moving wave)
kentic energy- energy in motion
Type of resources that is inexhustable
Wind, Geothermal,Solar, Biomass, Hydropower
renewable
2. When the 2 objects/substances reach the same temperature, they are at _________
thermal equilibrium.
Which is Conduction
Transfer of heat between two objects that are TOUCHING. As the particles of the hote object collide with the particles around it, it gives them their energy.
Cooking in a skillet (frying pan)
Burning your mouth eating hot food
Heating clothes you are ironing
Melting chocolate in your hand
type of energy is energy released during nuclear fusion or fission.
Nuclear energy is energy released during nuclear fusion or fission.
Examples:
Fusion is bonding of atoms together to create a new substance
The sun creates heat and light using nuclear FUSION.
FISSION is the splitting of atoms that cause a release of heat.
Greatest Potential and Greates Kinetic.
W= Greatest Potential Energy and Least Kinetic Energy
Z= Greatest Kinetic Energy and Least Potential Energy
4 examples of nonrenewable energy
Coal,Oil,Natural Gas, Nuclear
4. Heat moves like this in a convection current
the movement of heat through a fluid. Hot rises and cold sinks
3 energy transfers in order to make a fashligh shine.
Stored energy or energy of position
A rollercoaster at the top of a hill has more _____ than at the bottom
potential energy
5 examples of renewable energy
Wind, Geothermal,Solar, Biomass, Hydropower
5.Conduction
Transfer of heat between two objects that are TOUCHING. As the particles of the hot object collide with the particles around it, it gives them their energy.
Cooking in a skillet (frying pan)
Burning your mouth eating hot food
Heating clothes you are ironing
Melting chocolate in your hand
Type of energy is heat that is caused from movement of atoms and molecules.
Thermal energy
Kettle, Irons, Stove
Basically any object that emits heat
Heat generated from friction
electromagnetic waves that are visible to the eye.
Light energy
this creates greater kinetic energy
Greater speed = greater kinetic
Greater mass = greater kinetic
