Computing: Gas II

Gases have always intrigued humans, from ancient beliefs linking intestinal gases to the human spirit to modern scientific explorations. Gases consist of rapidly moving particles that possess mass and are the least compact form of matter. They can be measured by properties such as pressure, volume, temperature, and amount. The kinetic molecular theory explains that gas particles are in constant motion and occupy a volume much larger than the actual space the particles themselves take up. Understanding these characteristics can help differentiate gases from solids and liquids.

  1. Computing:Gas II Booting up……….

  2. What is it about gases? • Gases have always been a mystery to humans • Ancient tribes thought that intestinal gases were part of the human spirit and that being gassy meant that their spirit was upset.

  3. Compu-Com: What are some characteristics of gas?

  4. What is it about gases? • Gases are made of particles that move randomly and rapidly • Gasses have mass • They are the least compact form of matter

  5. What is it about gases? • Gases are made of particles that move randomly and rapidly • Gasses have mass • They are the least compact form of matter • Gases are measured with certain properties • Pressure • Volume • Temperature • Amount of gas

  6. Kinetic molecular theory A gas consists of small particles (atoms or molecules) that move randomly and with rapid velocities The attractive forces between the particles of a gas can be neglected. The actual volume occupied my gas molecules is extremely small compared to the volume that gas occupies The average kinetic energy of gas molecules is proportional to the Kelvin temperature Gas particles are in constant motion, moving rapidly in straight paths. (take a deep breath….we just have to get through this part)

  7. Computing: What makes a gas different than solids and liquids?
