Potential energy and energy transfer.
What is chemical energy? And some examples of it.
energy stored in molecules and bonds, when bonds are broken energy is released.
food, chemical energy, photosynthesis, coal, oil, battery's, and gas.
What are Potential energy and kinetic energy?
Kinetic energy:The energy an object has due to its motion depends on mass and speed.
Potential energy:The stored energy is an object due to where it is, position/location. Depends on location- the higher an object is from the ground, the more potential energy it has.
What are some examples of non renewable sources?
Coal
Nature gas
Nuclear energy
Fossil fuel
Gasoline
Oil
petroleum
What is the personality of Solids
•
tightly packed,
• vibrating.
• in a fixed position.
Finish the sentence:
“Electrons orbits _________ the nucleus as they __________________”
“(fly the positive proton around)”, “are repelled from the positive protons.”
Full sentence “Electrons orbits (fly the positive proton around) the nucleus as they are repelled from the positive protons.”
What is nuclear energy? And examples. And name 4 Forms of Potential Energy.
Nuclear energy is the energy stored in the nuclear atom.
the sun power, plant power, fission (foming).
Potential energy and kinetic energy, How are they different?
Kinetic energy is energy that is being used.
And potential energy is being stored.
How is Oil made
Liquid
Dead Sea animals, plants
Made under harsh conditions
Depends and deposits.
What is a solid’s shape and volume?
Solids have a definite shape and a definite volume.
What is Viscosity? And examples of higher and lower viscosity!
Viscosity-how easy a liquid flows.
Lower Viscosity:water, soda, juice, sunny d.
Higher Viscosity: honey, oil, syrup, ketchup, mustard.
What happens when chemical energy gets out, what does it become?
Mechanical energy.
What are 2 forms of kinetic and potential energy
Kinetic energy
Thermal energy and radiant.
Potential energy
Nuclear energy and chemical energy
How is Coal made? And 2 examples!
Plants died, plants were burned under water, and heat pressures made coal, coal made swamps
Ex: oil, and Coal
What are Two types of solids? And How are they arranged?
Crystalline-Atoms are arranged in a repeating pattern.
Amorphous-atoms are randomly arranged;non repeating patterns.
What is Surface Tension?
water molecules at the surface are strongly attracted to one another (known as cohesion) and stick together forming a thin layer of "skin" on the surface.
What happens when electrical energy gets out, what does it become?
It becomes radiant energy.
What is electric and mechanical energy?
Electric: electrical energy is the moving energy carried by an electric current.
Mechanical:energy of motion or position, anything moving KE
Why is solar energy and wind different from fossil fuel? Explain!
It is because Solar and Wind are renewable resources but fossil fuels are not renewable, non renewable resources.
Finish the sequence:
“Matter can’t ___________________________________ only change its form.”
“be created nor destroyed, it can”.
Full sentence,”matter cannot be created nor destroyed, it can only change its form”.
GAS, how do they interact? do they have an indefinite or definite shape and volume?
"Particles of gasses are very far apart. " Gasses have an indefinite shape and an indefinite volume.They move randomly and freely.
Example of chemical energy to mechanical energy.\
Food we eat becomes energy.
How are electric and mechanical energy related and different?
Related: they are forms of kinetic energy.
Difference:electric energy is energy that is moving by electric waves or currents and mechanical energy is the motion that moves KE.
How is coal made? In detail please! And is coal a renewable resource or a nonrenewable resource?
Coal comes from ancient times where dinosaurs were on the brink of extinction, the dinosaurs got stuck in swamps and there body’s and dead plants were buried or burned under the water and the heat pressure trapped them tightly together to create coal, which is non renewable energy.
Particles of liquids are…
•
tightly packed, but are far enough apart to slide over one another.
• Liquids have an indefinite shape but a definite volume.
Three Subatomic particles:
- Protons (+)
- Neutrons
- Electrons (-)
