PHYSICAL SCIENCE WEEK 1 description and overview PPT.pptx

Collision theory is a principle in chemical kinetics that explains how and why reactions occur at the molecular level. It states that for a reaction to take place, the reactant particles must collide with each other under the right conditions. The key aspects of collision theory include:

1. Evolution of the understanding of Matter, motion, electricity, magnetism and light and the universe from ancient time to present. Application of Physics and Chemistry concepts in context such as atmospheric phenomena, cosmology, astronomy, vision, medical instrumentation, and sources of energy.
