Intro to Energy
the ability to cause change
what is energy
measure of the average kinetic particles in an object
what is temperature
is the total kinetic energy of all particles in a substance
what is Thermal Energy
sum of an objects kinetic and potential energy
what is mechanical energy
kinetic energy of particles move faster at higher temperatures
what is thermal energy
energy of an object due to its motion depends on its mass and speed
what is kinetic energy
particles that are close - not free to move much
what is a Solid
heat is the energy transferred from an object at ________ temperature to an object at a _______ temperature?
what is higher to lower
vibration of particles in a medium
what is sound energy
the uses degrees to represent temperature except for
what is Kelvin
energy of an object has to due to its position, condition or chemical composition
what is potential energy
moves & slides/tumbles over each other
what is a liquid
transfer heat by electromagnetic waves
what is Radiation
electromagnetic waves through space
what is electromagnetic energy
energy source is atoms nucleus - releases energy when breaks or bonds join
what is nuclear energy
what is the measurement of Energy
what is Joules
particles are far apart collide with each other
what is GAS
direct contact VS transfer of heat by movement of gas or liquid
what is Conduction vs Convection
results from position or motion of charged particles
what is electrical energy
water boils at 212
water freezes at 32
and human body temp is 98.6
what is degrees Fahrenheit
what is an energy transformation?
what is energy changes from one form to another
water boils at 373 and freezes at 273 and the human body temp is 10
what is Kelvin
the amount of energy needed to raise the temperature of 1g of water to 1 degree Celsius
what is a Calorie
atoms and their arrangements
what is chemical energy
what is the degree in which water boils and freezes and what the body temp is in Degrees Celsius
what water boils at 100 degrees celsius
water freezes at 0 degrees celsius
human body temp at 37 degrees celsius
