Question

what temperature units should be used when performing calculations using any gas law? °c only k only °c, k, or °f

Explanation:

Gas laws (e.g., ideal gas law, Boyle's law) require absolute temperature scales because they relate temperature to molecular kinetic energy, which cannot be negative. The Kelvin (K) scale is absolute (0 K = absolute zero), while Celsius (°C) and Fahrenheit (°F) are relative and can have negative values, making them invalid for gas law calculations.

Answer:

K only
