2C-Heat & Thermodynamics Flashcards
temperature
the measure of heat energy in a system; the measure of the average energy
heat
thermal energy that is moving from hot to a colder temp
thermal energy
type of energy that is stored in an object, it is a measure of the random kinetic energy of each atom in the object; total energy
Rudolf Clausius
German physicist proposed the 1st law of thermodynamics - (conservation of energy law)the total amount of energy in a closed system is constant
also the 2nd Law-that in a closed system, energy flows from a hot area to a colder area
Specific heat
the amount of heat required to increase the temperature of a unit mass of a substance by 1-degree celsius. lower specific heat, larger the atoms
