Definition of Resistance and temperature
Check what you remember
Read the wording for your board, then hide it and explain Resistance and temperature in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
In a metal, higher temperature makes the ions vibrate more strongly, which increases the number of collisions with the moving electrons and so increases resistance.
