Theory and troubleshooting using short modules packed with images to make learning quick and easy.
People often say heat rises, but that’s not entirely true. While hot air weighs less than cold air and will naturally rise, heat travels in all directions; from hot to cold. Heat flows between substances when there’s a difference in temperature. If you leave a 32°F ice cube sitting in a 69°F room, heat from…
