Energy key terms

?
potential energy
stored energy (that can be changed)
1 of 13
conservation
energy in a system remaining constant
2 of 13
specific heat capacity
energy needed to raise the temperature of 1Kg of a substance by 1°C
3 of 13
conduction (solids)
vibrating particles transfer energy to neighboring particles
4 of 13
convection (liquids and gasses)
energy particles move from hotter to cooler regions.heated particles rise because they are less dense as the collisions cause them to have more space between them and as the heated particles rise cooler particles replace them and the process repeats.
5 of 13
closed system
no energy leaves the system but it is transferred within. net change in the total energy is always 0 as no energy is lost or gained
6 of 13
work done
energy transferred
7 of 13
conservation of energy principle
energy can be transferred, stored or dissipated but can never be created or destroyed
8 of 13
dissipated energy
wasted energy
9 of 13
power
rate of energy transfer/ rate of doing work
10 of 13
non-renewable energy resources
will run out one day. do damage to the environment. provide most of our energy.
11 of 13
renewable energy resources
will never run out. damage the environment less than non-renewable. don't provide as much energy and are unreliable if dependent on the weather
12 of 13
bio-fuels
renewable energy resources made from plant products or animal waste
