Lecture 4: 09.16.05 Temperature, heat, and entropy
... •� Work and heat are not state functions; they are path dependent- what does this mean? In most physical situations, we are concerned with a quantity of heat or work transferred into or out of a material, which causes a change from one state of the material to another. Path dependence implies that t ...

... US2 Air in a piston cylinder undergoes a three process cycle. Initially, the air has a specific volume of 3cubic meters per kg and a pressure of 120kPa. The air is compressed and heat is removed for an isobaric process until the volume is reduced to one third of its original volume. Next the air is ...

What is Energy?
... The term "joule" is named after an English scientist James Prescott Joule who lived from 1818 to 1889. He discovered that heat is a type of energy. One joule is the amount of energy needed to lift something weighing one pound to a height of nine inches. So, if you lifted a five-pound sack of sugar ...
