I keep getting “Kinetic theory of gases” questions wrong in Thermodynamics & Kinetic Theory. What's the trap?
using Celsius instead of Kelvin in gas relations.
The usual trap: using Celsius instead of Kelvin in gas relations. How to avoid it: always convert temperature to Kelvin for PV=nRT. Go back to the definition — gas pressure comes from molecular collisions, and average molecular KE is proportional to absolute temperature.
Key point
Kinetic theory of gases
Common mistake
using Celsius instead of Kelvin in gas relations.
Memory tip
always convert temperature to Kelvin for PV=nRT.
