Kelvin Scale: A temperature scale that starts at absolute zero (-273.15ยฐC) and uses the same size units as Celsius.
Standard Conditions: Defined conditions used for comparing and reporting data, including a pressure of 1 atmosphere (atm) and temperature of 298 K.
Absolute Zero: The lowest possible temperature, -273.15ยฐC or 0 Kelvin, where molecules have minimum energy and motion ceases.
