Energy And Heating Flashcards
What is transmitted as energy is transferred through a substance?
Conduction convention or radiation
What is an insulator?
The material that will not allow the easy flow of energy
What is a conductor?
A material that allows and internal energy to be transmitted through it easily
What is thermal conductivity?
The measure of how well material conduct electricity when heated
What is thermal conductivity measured in?
Watts per metre per degree Celsius, w/m/*c
What is temperature a measure of?
The average kinetic energy of the molecules
What does different materials requiring different amounts of energy needed to change temperature depend on ?
The mass of the material substance of material and the desired temperature change
What is specific heat capacity?
The amount of energy needed to raise the temperature of 1 kg of a substance by 1°C
What is specific heat capacity measured in?
Joules per kilogram per degree Celsius,J/Kg*c
What is the calculation for energy transferred?
Energy transferred equals potential difference times current times time
