Firefighters need a strong understanding of chemistry for personal and public safety, to enhance the effectiveness of their efforts and to prevent adding to the many hazards present during a fire. A firefighter uses his or her understanding of the chemistry of building materials and furnishings as well as the interaction of suppression chemicals with fire.Know More
Firefighters use chemical principles on a daily basis, especially when choosing the right type of extinguisher in combating chemical or industrial fires. They must apply the right type and amount of extinguisher to fires. Some substances burn more intensely and more dangerously, even exploding violently in the presence of certain types of substances. Electrical and petrochemical fires, for example, cannot be extinguished with water. Some compounds such as metallic sodium and magnesium actually explode when exposed to water. This requires firefighters to understand the chemical properties of the substances that are present within the fire as well as those used to put the fire out.
Firefighters also use chemistry when protecting the public from the potentially hazardous substances produced in fires and released in chemical spills. Firefighters need to understand how to mitigate the risks to themselves and the public while also knowing how to treat those exposed or injured.Learn more about Chemistry
Chemistry is the scientific study of the composition, properties and interactions of organic and inorganic matter. Chemistry is commonly used in fields of science and medicine, according to About.com.Full Answer >
The Kp in the study of chemistry is an equilibrium constant of both heterogeous and homogeneous gaseous reactions, according to ChemGuide. Value is determined by the partial pressures of the gases inside a closed system.Full Answer >
Polarity is a physical property of compounds which relate to other physical properties, such as melting and boiling points or solubility. Bond polarities arise from bonds between atoms of different electronegativity. A molecule can be ionic, polar or non-polar.Full Answer >
