Intro to Thermodfluid

Question 1

Zeroth Law of Thermodynamics

Answer 1

If two bodies are in thermal equilibrium with a third body, then they are also in thermal equilibrium with each other

Question 2

First Law of Thermodynamics

Answer 2

• Conservation of energy principle

- During an interaction, energy can change from one form to another but the total amount of energy remains constant

Question 3

Second Law of thermodynamics

Answer 3

Energy has quality as well as quantity, and processes occur in the direction of decreasing quality of energy.

Question 4
