Energy Transformation
What form of energy transformation does a toaster produce?
Electrical to radiant to thermal
The 3 forms of heat transfer.
Conduction, convection, radiation
About what percentage of the Sun's energy reaches the surface of the Earth?
About 50%
How many particle parts do atoms have?
3; protons, neutrons and electrons
What is radiant kinetic energy?
Why can the amount of potential and kinetic energy change?
Depending on the placement of the object.
What is conduction?
When heat transfers/moves from one object to another by touching another.
True or False: The Atmosphere reflects a lot of the Sun's rays.
True
What particles are in the nucleus of an atom.
Protons and Neutrons
What form of matter describes solids?
Molecules are tightly packed and have a fixed shape.
What are the six forms of potential energy?
Gravitational potential energy, nuclear potential energy, magnetic potential energy, static potential energy, elastic potential energy, and chemical potential energy.
What is convection?
When heat transfers through air or water by the less dense warm air/water rising and the more dense cold air/water falling.
What is reflection?
When light/heat/sound/gasses bounce off one thing and do into a different direction.
What are electrons?
Negatively charged particles that circle around the nucleus.
What objects can describe liquids?
orange juice, milk, water, and liquids
Is a curling iron able to transform heat from one object to another.
Yes because the heat from the iron curls your hair and makes it warm.
What is radiation?
The flow of electromagnetic waves between objects that are not touching each other.
What is absorption?
When something soaks up heat/liquid/gasses/and or light.
What are protons?
Positively charged particles.
What is a gass?
A form of matter in which the molecules are very spread out, move a lot, and have no fixed shape.
What are the five forms of kinetic energy?
Mechanical kinetic energy, thermal kinetic energy, electrical kinetic energy, sound kinetic energy, radiant/sound kinetic energy.
What is energy?
the ability to do work
What are the four things that have the do with reflection and absorption?
Light/liquid/gasses/and or sound
What are neutrons?
Particles found inside the nucleus that have no charge.
What are the laws of the conservation of energy?
1. Energy can not be created or destroyed.
2. Energy may not change form, but the total amount remains the same.
3. Energy can be changed from one to another, and that is known as energy transformation.
