Collision theory 1970-01-01
Collision theory is a fundamental concept in chemistry that explains how chemical reactions occur. According to this theory, for a reaction to take place, the reactant molecules must collide with each other. However, not all collisions lead to a reaction; specific conditions must be met. Here are the key components of collision theory: 1. **Collision Requirement**: Reactant particles must collide for a chemical reaction to occur. The rate of reaction increases with the frequency of collisions.
Port-wine stain 1970-01-01
A port-wine stain is a type of vascular birthmark characterized by a flat, red or purple discoloration of the skin. These marks are caused by an abnormal proliferation of blood vessels, specifically capillaries, just beneath the surface of the skin. The name "port-wine stain" comes from the deep red color that resembles port wine.
