Energy Flashcards
What is the Law of Conservation of Energy?
Energy can neither be created nor destroyed only transferred from one form to another

What is Convection?
The heat transfer by molecules which are free to move through the medium
What is Conduction?
Heat is transferred from atoms that are touching
What is Specific Heat Capacity?
Quantity of heat (joules) required to change the temperature of a unit mass by 1 degree
What 2 things affects the energy required or lost by a material?
The mass of the object
The type of material
