Year 11 - Heating processes

Question	Answer
Kinetic particle model	a model that describes the behaviour of matter in solid, liquid and gas states
heat	the transfer of thermal energy from a hotter body to a colder one
temperature	the measure of the internal energy of a system
thermal energy	the internal energy of an object due to the kinetic energy of its atoms and/or molecules
internal energy	refers to the total kinetic and potential energy of the particles within a substance
heating...	...increases the internal energy of a substance by affecting the kinetic energy and/or potential energy of the particles within a substance
kinetic energy is...	...the energy of motion
potential energy is ...	... the energy that is stored in an object due to its position relative to some zero position
thermal equilibrium	for two bodies in thermal contact, the point at which the two reach the same temperature and there is no further net transfer of thermal energy
thermal contact	when two objects are in contact so that energy exchange via heat transfer is possible
zeroth law of thermodynamics
