Temperature as a measure of internal energy
What Temperature as a measure of internal energy means in Physics A-Level, as defined for OCR.
Definition of Temperature as a measure of internal energy
Check what you remember
Read the wording for your board, then hide it and explain Temperature as a measure of internal energy in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Internal energy depends only on the temperature and on the number of molecules, not on the type of gas, so doubling the thermodynamic temperature of a fixed amount of ideal gas doubles its internal energy.
