THERMO CHAPTER 1

It is a foundational branch of physical science that explores the behavior of energy and its interactions with matter.

• Mechanics

• Thermodynamics

• Kinetics

• Electromagnetism

It refers to the fundamental measures such as mass, length, time, and temperature that describe any physical quantity.

• Dimensions

• Variables

• Constants

• Systems

It is a standardized system of measurement based on decimal relationships and standardized prefixes, such as kilogram and meter.

• English System

• CGS System

• International System (SI)

• Metric Imperial System

It is the constant that underpins all thermodynamic calculations, represented by 8.314 kJ/mol-K.

• Boltzmann Constant

• Gravitational Constant

• Universal Gas Constant

• Planck’s Constant

It is the requirement that every term in an equation must have the same unit, ensuring correctness in analysis.

• Unit Balance

• Dimensional Homogeneity

• System Consistency

• Formula Accuracy

These are unitless ratios equal to one that can be inserted into calculations to convert units properly.

• Conversion Tables

• Unity Conversion Ratios

• Dimensional Constants

• Correction Factors

It is a specified quantity of matter or a region in space selected for analysis in an energy or mass-interaction problem.

It is a thermodynamic system that can neither exchange matter nor energy with its surroundings.

• Open System

• Closed System

• Isolated System

• Steady System

These are macroscopic quantities that describe a system’s physical condition at any given time.

• Properties

• States

• Variables

• Constants

It is achieved when a system’s macroscopic properties do not change over time and there are no unbalanced potentials.

• Steady Flow Process

• Thermal Balance

• Thermodynamic Equilibrium

• Static Stability
