Question

13.1 Charge Charge is quantized: quantum of charge e 1.6 x 10-19 C (coulombs). Any charge qtne,n- integer. Total charge is conserved in an isolated system. In these problems, ignore gravitational attraction between objects unless mentioned. explicitly 1. Name a few things in your real-life experience that are quantized, ie. are an integer multiple of some smallest quantity 2. When you balance a chemical reaction, you make sure that what is/are the same on both sides of the chemical equation? Why?

Answer 1

In real life, the movie frame (smallest amount of movie), the pixel (the smallest part of a digital picture, tree (smallest part of a forest), a letter (smallest part of world) are few quantized things. Masses and charges should be equal on both sides because they are conserved quantity and they can be neither created or destroyed.
