I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change‚ color change‚ bubbles or gas‚ irreversible‚ temperature changes and finger prints. By the end of the lab‚ my goal was to be able to didtinguish easily the difference between chemical and physical changes. Question #1 answer. 1. Gas. 2. Dissolved in water. 3

Geometry in Everyday Life Geometry in everyday life Geometry was thoroughly organized in about 300bc‚ when the Greek mathematician‚ Euclid gathered what was known at the time; added original work of his own and arranged 465 propositions into 13 books‚ called Elements. Geometry was recognized to be not just for mathematicians. Anyone can benefit from the basic learning of geometry‚ which is to follow the lines reasoning.

Chemical changes are irreversible because substances mix and cause a reaction which creates a new substance. Chemical changes can be caused when a substance is combined with a heat‚ water or another substance. Heat can cause a chemical reaction called caramelisation which is when sugar is heated at a high temperature causing it to break down. This gives the sugar a nutty taste and causes it to brown. Physical changes are changes that change the physical appearance‚ smell and

I get refreshed with the morning walk or a little exercise and then prepare myself for the study with utmost sincerity. It is against my principle to put off today’s work for tomorrow or to have any private tutor

POLYNOMIALS IN DAILY LIFE Polynomials are a combination of several terms that can be added‚ subtracted or multiplied but not divided. While polynomials are in sophisticated applications‚ they also have many uses in everyday life. Although many of us don’t realize it‚ people in all sorts of professions use polynomials every day. The most obvious of these are mathematicians‚ but they can also be used in fields ranging from construction to meteorology. Polynomials in Construction and Material
