Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
- Extreme wind will cause windows to shatter and burst outwards. Explain which principles of physics govern this phenomenon and how it occurs.
- Two 2-liter soda bottles each have a tiny pinhole near the bottom. One bottle has the cap firmly in place on top, and the other bottle is open. Which bottle will leak less/more and why?
- You are on a hike and see a babbling brook. It seems to narrow from about 2 meters wide to 4 meters wide. What can you say about the velocity of the water as it moves from the narrow area to the wide area of the brook?
