Document Summary
Topics covered: 1. 1 chemistry in context, 1. 2 phases and classification of matter. Matter any object that has mass, and occupies space. Energy capacity of power to do work. Chemistry the study of the relationship between matter and energy. Scientists follow a set of guidelines known as the scientific method. The scientific method starts when you ask a question about something that you observe how, what, when, who, which, A hypothesis can be defined as a prediction in the attempt to. There are times when predictions are not accurate, and hypotheses answer the outcome in the experiment you are about to conduct are not supported. If that is the case, a scientist will go back and construct a new hypothesis based on the data learned from the first trial of the experiment. Solids have a fixed volume & fixed shape. Liquids have fixed volume & variable shape. Gases have variable volume & variable shape.
