Chapter 1

What is thermodynamics

Study of heat, work, and phases/states of matter

Closed System

No mass flow (control mass)

Open System

Mass and energy flow (control volume)

Isolated System

No mass nor energy flow

Surroundings

Everything external to the system, separated by boundary

How is a boundary shown

dotted line

Property

characteristics of a system with a numerical value at a given time: independent of system's history

Intensive property and example

Independent of amount of matter/mass

Ex: Density, temp, pressure, color

Extensive property and example

Dependent of amount of matter/mass

Ex: Volume, mass, energy

Process

change a system undergoes from one Eq state to another

Path

how it gets to one Eq state to another

Quasi equilibrium

Process where properties change very slowly between Eq state: treat as Eq

Specific volume

volume per unit mass: 1/rho

Zeroth Law of Thermo

two objects in thermal Eq with a 3rd, they are all in Eq with each other
