What are the derived units of density? Thus density is an intensive quantity. The SI derived unit for density is the kilogram per cubic meter (kg/m3). This unit is awkwardly large for most chemical applications. The unit g/cm3 and its equivalent, g/mL, are more commonly used for solid and liquid densities. Which one is derived […]

What kind of energy is a glowing firefly? This type of light production is called bioluminescence. The method by which fireflies produce light is perhaps the best known example of bioluminescence. When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced. What […]
