Disclaimer: Due to unforeseen difficulties, we have had to take down the images on this notes page. They can also come from medical equipment, such as X-rays. Atoms are the fundamental building blocks of matter and are composed of protons, neutrons, and electrons. A chemical element holds the same number of protons, which corresponds to its atomic number. This gives it a non-zero charge.

Build your knowledge and consider the issues surrounding nuclear power. A Vacuum flask has many features to reduce not only thermal radiation but also conduction and convection.

Today, we take a quick look into infrared radiation,.
