what is thermodynamics? The study of the changes in energy and transfer of energy that accompanies physical and chemical processes.
what is energy defined as? energy is the ability to do work
what are the different type of energy? Mechanical, electrical, radiant, nuclear and chemical
what is Heat? heat is the measure of internal energy that is absorbed or transferred from one body to another
what is internal energy? The total kinetic energy and potential energy of all the molecules or an object.
what does the first law of thermodynamics state? The first law of thermodynamics state the total energy of the universe is constant
what is the first law of thermodynamics also known as? It is referred to as the law of conservation of energy

what does the law of conservation of energy state? Energy cannot be created or destroyed, but it can change from one form to another
Change in internal Energy of closed system = Q (heat flow) + W (work done)
what is one significance of the first law of thermodynamics? the total amount of energy in a universe remains constant
what is the first law of thermodynamics also known as? it is also known as the law of conservation of energy
what does the second law of thermodynamics deal with? This law deals with thermal equilibrium
what does the second law of thermodynamics state? Second law of Thermodynamics states that in any spontaneous process the entropy of the universe increases.
Heat can only spontaneously transfer from? hot to cold objects.
The total change of entropy equal to? change of the entropy of the system + the change in entropy of the surrounding. This total must be more than zero.This explains why some reactions that obey the first law of thermodynamics then do not react
what is the second law of thermodynamics also known as? it is known as the law of Entropy
what does the third law of thermodynamics state? The third Law of Thermodynamics states that any substance at a temperature of absolute zero has an entropy of zero.This means that absolute zero is difficult to be reached. i.e zero kelvin
what is the third law of thermodynamics also known as? it is known as the law of Absolute Zero
