Post Basic thermodynamics' question

Posted 2003-12-08, 01:28 PM
One liter of water (1 kg, 10ºC, c=4180 J/(kg*K)) is stored in a 25ºC bowl with a mass of 0.5 kg and a heat capacity of 2500 J/(kg*K). The water is heated up with the effect 100W for 1 minute (6,000 J). What will the end temperature of the bowl be? Assume that only the water and the bowl exchange heat.

I don't have the brain for math stuff, to me this is greek.. which means math is a language i don't care to understand... this sounds more like physics but again... i hate it :P

It is Physics and you'd have to know the equation to do it.

I'm thinking either E=cm*(delta t) + cm*(delta t), where the first cmt is represented by the bowl, and the second one is represented by the water.

Either that, or cm(T-x1)=cm(x2-T) could prove useful. Ugh. I'm stuck though.
