PPT-Chapter 2 Science, Matter, Energy, and Systems

Science is an endeavor to discover how nature works It has limitations and hypothesis are tentative and testable statements that must be capable of being supported or not supported by observational evidence.

Extensive Properties: depend on amount of matter in a sample. Mass: amount of matter. Volume: space occupied. Intensive Properties: depend on type of matter, not amount. Density: mass/volume. Matter and Energy What is matter? Matter and Energy What is matter? It's what everything that occupies space and has mass is made of And everything like that is made out of chemical elements There are 92 naturally occurring chemical elements, and a number of synthetic ones Module H Unit 1: Matter Lesson 1: Introduction to Matter Matter - anything that has mass and takes up space. Matter makes up the materials around you. Mass - the amount of matter in an object. Even air has mass. . Dan Hooper . – . Fermilab. Saturday Morning Physics. What is Physics?.
