In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

This video explains the concept of thermal conduction, which is the transfer of thermal energy through solids. The video discusses the three main mechanisms of thermal energy transfer, thermal conduction, convection and thermal...

Today we’re talking about heat transfer and the different mechanisms behind it. We’ll explore conduction, the thermal conductivity of materials, convection, boundary layers, and radiation.

This is a lecture video on thermal insulation that discusses how energy can be lost from a building and the measures that can be taken to reduce this loss. The video covers various parts of a building such as the roof, windows, and...

The video is a lecture on convection. The lecturer explains the three main mechanisms of thermal energy transfer - thermal conduction, convection, and thermal radiation - and focuses on the latter. Through the use of examples, the video...

This thermal conductivity demonstration can form the introduction to developing ideas about energy transfers between objects, and their specific heat capacity. Register for over 8,000 FREE teaching resources available from the National...

This video is about thermal radiation and how thermal energy is transferred by infrared radiation. The video also explains how different surfaces absorb and emit infrared radiation and their effect on the transfer of thermal energy. The...

This video explains how thermal energy is transferred by infrared radiation and compares the ability of different material surfaces to absorb and emit this radiation. Examples of different objects and surfaces are given to illustrate...

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!

What is it? ... It's a radiator!

The thermal mass of an object is its ability to store or absorb heat. Things that are considered ‘difficult’ to heat generally have a high thermal mass. Brick or concrete, for example, heat up only after they’re provided with a lot...

The pirates are off to find more treasure! Will they make it across the stormy seas? This lesson will survey the physical properties of metals, non-metals and metalloids. Definitions included: physical property, standard ambient...

The video focuses on the concept of energy dissipation and how it occurs in various systems. It begins by explaining the principle of conservation of energy and then goes on to provide examples of closed and open systems. The video then...

How do laptops stay cool? we look inside a laptop to learn how a laptop heat pipe works to control the thermal management of a laptop and remove the heat from the processor.

The need to see in the dark; to observe weather patterns from outer space; or to conduct security surveillance at night, lead to the Big Idea of Night Vision, and Thermal Imaging. FLIR, or Forward Looking Infra Red, is a continuation of...

Dr. Forrester talks about thermal energy. She defines thermodynamics and talks about conduction, convection, and radiation. She also defines photovoltaic energy. She talks about solar power and then shows how to make a solar oven.

Four substances are shown on screen, but which is the odd one out and is not a good conductor of heat?

Some chefs swear by copper pots and pans, but they are much more expensive than other materials. Are they worth it? Well, it all comes down to electrons!

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep your warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks...

Conduction, convection and radiation are all ways in which heat is transported. How does each work, and what are they useful for? Physics - Energy And Radioactivity - Learning Points. The three types of heat transport are conduction,...

Dr. Forrester describes potential energy by examining such energies as gravitational, sound, and thermal. She also observes potential energy by conducting an experiment.

How does NASA "see" thermal radiation? This video explores what infrared energy is and how NASA detects it to study our Earth's systems more completely. Satellite measurements over time allow scientists to study seasonal changes in...
