A

absorption

when a material takes in electromagnetic radiation or particles.

albedo

the reflectivity of a surface. It quantifies the fraction of incoming light or radiation that is reflected back into space. It's like a celestial fashion statement, showcasing how much light a surface chooses to bounce back.

expressed as a value between 0 and 1, or sometimes as a percentage between 0% and 100%

= \( \frac{reflected \ radiation}{incident \ radiation} \)

apparent brightness

inversely proportional to the square of the distance between the object and the observer.

= \( \frac{luminosity}{4 \pi d^2 } \)

Avagadro constant

approximately equal to 6.022 x 10²³ particles per mole. It's like a cosmic numerical bridge that allows us to quantify the vastness of the microscopic world.

average kinetic energy

directly proportional to the temperature of a gas. As the temperature rises, the particles gain more energy and move with greater speed. It's like a temperature-driven tango, where the dance becomes more lively as the heat turns up.
