Question

in order to solve gas law calculations, temperature must be measured in: celsius it doesnt matter kelvin fahrenheit

Explanation:

Gas law calculations, such as the ideal gas law \(PV = nRT\), require temperature to be in the Kelvin scale. This is because the Kelvin scale is an absolute temperature scale (where \(0\) K represents absolute zero, the lowest possible temperature). In contrast, Celsius (\(^{\circ}\text{C}\)) and Fahrenheit (\(^{\circ}\text{F}\)) are relative scales (they have arbitrary zero points, like the freezing point of water for Celsius). Using relative scales in gas - law equations would lead to incorrect results. For example, if we use the combined gas law \(\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\), substituting \(T = 0^{\circ}\text{C}\) (which is \(273.15\) K) would give a wrong physical interpretation if we didn't convert it to Kelvin first.

Answer:

Kelvin
