WebOct 11, 2009 · Answer. Usually, when things freeze - in other words turn from a liquid into a solid - they shrink or get smaller. This is because, normally, if you make something hotter, it vibrates more. When it vibrates more, it tends to take up more space, so it tends to expand. So, logically, if you cool something down, then the particles should move more ... WebIt expands. Take a normal disc, and draw a circle on it. The circle expands. Take a new disc, draw a hole, and make a score on that circle. It still expands. Repeat with deeper scoring. It still expands. Keep making it deeper. It still expands. At one point, your razor(or whatever) will start poking through the metal. It still expands.

WebJan 14, 2016 · 3 Answers. When plastic sheets are produced, they are rapidly cooled to keep the polymer chains oriented in a way that makes the sheets nice and flat. This is a relatively high-strain orientation since it is associated with the energy level of the molecules at the casting temperature. Once the plastic is heated above its glass transition ... WebA plasma is an electrically charged gas. In a plasma, some electrons have been stripped away from their atoms. Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields. This is the main difference between a gas and a plasma. jute twine firestarter
