The following are answers to questions from [[Question for Whole Course Concept Map (Four Basic Principles)]]. 
 
1) All substance are composed of particles (base units) that are in constant motion and sometimes interact/collide.
 
2a) Law of Conservation of mass 
Book def. - mass is neither created nor destroyed, in a physical/chemical change. 
What it means: must account/keep track of all the mass in a system. 
 
2b) Law of Conservation of Energy 
Book def. - energy is neither created nor destroyed, in a physical/chemical change. 
What it means: must account/keep track of all the energy in a system. 
 
3) the charges of two particles and how they interact. Same charged particle REPEL, different charged particle ATTRACT 
 
4) When two particles collide and rearrange into NEW grouping, it is a chemical change (called chemical reaction). 
 
When two particle collide and DO NOT rearrange and stay in same groupings, it is a physical change (called a physical process). 
 
5a) Rearrange what makes up particles (i.e. chemical change/reaction)- dealing with Intramolecular forces 
5b) No rearrange of base particles (i.e. physical change/process) - dealing with Intermolecular Forces 
 
6) Intramolecular Forces usually has more energy than Intermolecular Forces
