Energy Flashcards
What is the law of consevation of energy?
The law states that energy cannon be created or destroyed, only transferred.
total energy before = ?
total energy after

thermal energy
As we heat things the particles gain more ___ ___, and vibrate more or faster.
kinetic energy
The energy needed to heat an object depends on the …
mass, material and temperature rise.
Equilibrium is …
when objects have the same thermal energy.
What are renewable resources?
Resources that will not run out.
What are non-renewable resources.
A finite amount of resources created millions of years ago from fossils.
Give examples of renewable resources.
For example, wind, tidal, wave, hydroelectric, geothermal, biomass, and solar powers.
Give examples of non-renewable resources
Coal, oil, fossil fuels,or gas
How can thermal energy be transferred?
conduction, convection or radiation.
What happens to particals during conduction?
They collide with others when the vibrate due to the heat.
