StephenFord Posted July 10, 2022 Share Posted July 10, 2022 If you had a glass of water at 10c, and another glass of water at 30c, and set them both inside a room at 20c, which would reach room temperature 1st? Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted July 10, 2022 Share Posted July 10, 2022 I'm going to say the 30c glass. Warmer molecules move around more, using more energy. 1 Quote Link to comment Share on other sites More sharing options...

Now, I should have fessed up initially LOL I have an A level in both chemistry & physics, but I haven't a clue on this seemingly simple problem. Would be keen to know a definitive answer though 😂 Quote Link to comment Share on other sites More sharing options...
unofix Posted July 10, 2022 Share Posted July 10, 2022 Well after reading it twice and then realising it wasn't 10 cents & 30 cents, which I couldn't get my head around and finally realising it was the temperature I would think it requires more energy to raise the temp. So I think the 30C would cool quicker. Quote Link to comment Share on other sites More sharing options...

Oh stop it, what kind of fun is that, actually doing a 'practical' experiment! My old physics teacher would be proud of the suggestion though... 1 2 Quote Link to comment Share on other sites More sharing options...
