Question from my textbook: Jason says 'The mercury in the thermometer can be replaced by coloured water. The thermometer will function well after recalibrating using a similar method to calibrating a mercury-in-glass thermometer." Comment on his idea.
The answer is NO, but why?
Please use simple english to answer my question, as I am only grade 9, I haven't learnt much about physics, therefore I may not understand some technical words. Thanks!
