## What is Fourier’s Law of Heat Conduction?

Heat conduction is one of the three modes of heat transfer. In 1822, a French physicist published a treatise giving a complete theory and mathematical model. Who was he, and which mathematical formulation is he most famously known for?

## Introduction to Heat Transfer: Simple Experiments In Convection and Radiation

What are some simple heat transfer experiments that can be done to demonstrate convection and radiation?

## Introduction to Heat Transfer: Simple Heat Conduction Experiments

In this article, we discuss some examples of heat transfer mechanisms that occur simultaneously, and also simple heat conduction experiments you can do at home.

## What is Thermal Radiation Heat Transfer? Stefan-Boltzmann Equation

Why do you feel cooler if you white clothes instead of black ones on a hot sunny day? And why is the inside of a thermos bottle shiny instead of dull?

## Zener Diode Identification and Uses

A zener diode is a silicon diode that is optimized to conduct when it is reverse-biased. This article presents ways to identify one.

## What is Convection Heat Transfer?

By what process is heat transferred to the boiling water you use to steam vegetables such as a corn cob, or to your room when it is heated by a radiator?

## How does a potentiometer work?

A potentiometer is an electrical component with a variable resistance. This article discusses how they work, and how to use a multimeter to read one.

## Introduction to Heat Transfer: Conduction Part Two

How do your clothes keep you warm on a cold day? And why do rugs feel warmer to your feet than a tile floor that is at the same temperature? Could it be heat conduction at work?

## What is Thermal Conduction? Introduction to Heat Transfer: Part One

By what process is heat transferred when your hands become cold when you make a snowball or hot when you wrap them around a mug of coffee? Why are metals better heat conductors than plastic or wood?

## The Equation of State for Real Gases Part Five

What do airports, soda, and Nazi Germany have to with the van der Waals equation of state as applied to carbon dioxide?

## The Equation of State for Real Gases Part Four

An isothermal plot for an ideal gas shows one or more hyperbolas where PV is a constant. How is an isothermal plot for a van der Waals gas different?

## The Equation of State for Real Gases Part Two

In this article, we begin deriving an equation of state for real gases by using van der Waals’ modification of kinetic theory.

## The Equation of State for Real Gases Part One

The ideal gas law fails for gases that are near condensation. A physics graduate student
came up with a modified equation by amending the kinetic theory of gases. How did he do this, and who was he?

## The Postulates of the Kinetic Theory of Gases Part One

What are the assumptions underlying the kinetic theory of gases? Why are they important, and how does this relate to the ideal gas laws?

## The Postulates of the Kinetic Theory of Gases Part Two

What do bouncing billard balls, the unfortunate collision of a scarecrow with an electrical pole, and Boyle’s Law have to do with the kinetic theory of gases? This part explains how the collisions of molecules within a container lead to Boyle’s Law.

## Rogue Wave Implications and Role of Naval Architecture

Can a ship that is 956 feet and weighs 57,271 tons withstand the might of a monster wave bearing down upon it? You might be surprised to know that even modern naval architecture hardly takes into account the dangers to a ship due to monster waves

## Boyle’s, Charles & Gay-Lussac’s Law from Ideal Gas Law

The ideal gas law can be expressed in a number of ways. We can use one form of it to easily derive the laws of Boyle, Charles, and Gay-Lussac.

## Types of Recorded Rogue Waves

What are the different types of rogue waves? Where does physics fit into the equation, and what is the criteria for determining if a wave is “rogue” or “tame”?
