Chaptet 11-Energy Flashcards
What is the law of the conservation of energy state
It states that energy cannot be made or destroyed it can only be changed one form to another
How do scientist describe energy
Scientist describe energy as a property That something has which allows it to exert a force or to do work
What are the two kinds of energy
Potential energy, and kinetic energy
Potential energy and kinetic energy can be further divided into eight more types, what can potential energy be divided into (3)
Gravitational potential energy, strain energy, Chemical energy
What other kinds of energy can kinetic energy be broken into, five
Electromagnetic energy, internal energy, electrical energy, sound energy, and kinetic energy of moving bodies
What three parts does an energy transfer diagram have
Energy input in an hour, energy converter Or a transducer, energy output and an arrow
Give an example of Energy transfer diagram
Blowing up a balloon
Kinetic energy—>balloon—>strain energy
What are the two types of energy resources
Non-renewable energy resources and renewable energy resources
Name some nonrenewable energy sources
Fossil fuels, radioactive elements
Give some examples of some renewable energy sources
Waves, geothermal, wood fuel, solar, wind, hydroelectricity
How to heat and thermal energy move, three ways?
Conduction, convection, and radiation
What is conduction?
In conduction the heat energy passes from one particle in a substance to the next One it touches 🏐->🏐->🏐
Put gas solid liquid in order of conduction occurs Easiest to hardest and explain why
Conduction occurs The easiest in solids because they are close together, this is late and liquids because the particles move that, and hardly at all and gas is because the particles are too far away to touch one another
Where does conduction not take place
In the vacuum F out of space
Conviction only occurs in…
Liquids and gases
