Thermal Glossary

a cosmic daydream of gas behavior, a theoretical model that simplifies the complexities of real-world gases. It embodies a set of assumptions that make calculations and predictions in the realm of thermodynamics much more manageable.

characterized by a few key assumptions, such as negligible molecular volume and no intermolecular forces.

It relates the pressure, volume, temperature, and number of particles of a gas, capturing their interplay in a concise mathematical form.

expressed as follows: PV = nRT

The wavelength typically ranges from about 0.7 micrometers to 1 millimeter. That's like a cosmic scale of wavelengths, where the shorter wavelengths blend into the red end of the visible spectrum, and the longer wavelengths border on the microwave region.

the sum total of all the kinetic and potential energies of the gas particles.
