Chapter 18
The lowest temperature possible in nature is
-273 degrees C°
Entropy is closely related to the
2nd law of thermodynamics
A quantity of water has more entropy when it is
Boiling
The first law of thermodynamics is a restatement of
Conservation of energy
Systems that are left alone, tend to move toward a state of
More entropy
During an adiabatic compression of an ideal gas
No heat is supplied to or remove from the gas
Temperature inversion occurs when the upper layer of air are
Warmer than the lower regions
The greater the diff in temp between the input reservoir and the output reservoir for a heat engine, the
Greater efficiency
To wholly convert a given amount of heat energy into mechanical energy is
Impossible regardless of technology used
As a blob of air at a high elevation sinks to a lower elevation with. O heat input or output, it's temperature
Increases
As a system becomes more disordered entropy
Increases
Suppose you put a closed, sealed can of air on a hot stove burner. The contained air will undergo an increase in
Internal energy, temperature and pressure
