#### Thermodynamics - The second law of thermodynamics

20/3/2020· The second law of thermodynamicsThe first law of thermodynamics asserts that energy must be conserved in any process involving the exchange of heat and work between a system and its surroundings. A machine that violated the first law would be called a perpetual motion machine of the first kind because it would manufacture its own energy out of nothing and thereby run forever.

#### Heat Capacity - Specific Heat Capacity - Nuclear Power

Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system. Heat capacity C has the unit of energy per degree or energy per kelvin. When expressing the same phenomenon as an intensive property, the heat capacity is divided by the amount of substance, mass, or volume, thus the quantity is independent of the size or extent of the sample.

#### Third law of thermodynamics - Wikipedia

But clearly a constant heat capacity does not satisfy Eq. (12). That is, a gas with a constant heat capacity all the way to absolute zero violates the third law of thermodynamics. We can verify this more fundamentally by substituting C V in Eq. (14), which yields

#### Thermodynamics - The first law of thermodynamics

18/3/2020· The first law of thermodynamicsThe laws of thermodynamics are deceptively simple to state, but they are far-reaching in their consequences. The first law asserts that if heat is recognized as a form of energy, then the total energy of a system plus its surroundings is conserved; in other words, the total energy of the universe remains constant.

#### Thermodynamics Overview and Basic Concepts
