Thermodynamics Vocabulary

Question 1

Isentropic process

Answer 1

An idealized thermodynamic process that is both a diabetic and reversible

Question 2

Isobaric process

Answer 2

Pressure stays constant, the heat transferred to the system does work

Question 3

Adiabatic process

Answer 3

One that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. Energy is transferred to its surroundings in the form of work

Question 4

1st law of thermodynamics

Answer 4

The total energy of an isolated system is constant. Energy can be transformed from one form to another, but can neither be created nor destroyed

Question 5

2nd law of thermodynamics

Answer 5

The total entropy of an isolated system can never decrease over time

In all spontaneous processes the total entropy always increases and the process is irreversible

Question 6

3rd law of thermodynamics

Answer 6

The entropy of all perfect crystalline solids is zero at absolute zero temperature

Question 7

Entropy

Answer 7

Entropy is the expression of the disorder, or randomness, of a system, or of our lack of information about it.
