1. Hey all,

Really stuck on this idea I've had:
If i were to measure the temperature decrease of water in a beaker, how would changing the size of the beaker affect the temperature decrease over a unit of time, be it a minute or 30 minutes. For example if i made it wider, would the temperature decrease more over a unit of time or less?

EXAMPLE:
50ml of water in a 50cm^3 beaker
50ml of water in a 250cm^3 beaker
Given that both start at 80 degrees Celcius, which would have a lower temperature after 20 minutes.

Thanks in advance for the help.
2. ALSO,

It is clear to me that the results would be different to both. The question i'm really asking here is why they would be different?
