Looks to me like it's this simple:
So (200(25) + 150x) / 350 = 28Code:200 @ 25 150 @ x ======== 350 @ 28
An experiment involved in pouring 150g of heated copper into a 375 g aluminum cup containing 200g of water at 25 deg C. The mixture reached 28 deg C. What was the initial temp of the copper?
Is this Thermal equiliabrium?? mc delta T = mc delta T, but I have 3 items.
How do I compare 3 things?? Or do I do water to the cup and the copper to the cup??
Help if you can, thanks.
All I did was a simple "proportion", like:
buy 200 apples for 25 cents each, plus 150 bananas, for average price of 28 cents per fruit:
what's the price per banana?
But evidently not what you're after...
Perhaps a chemistry/physics expert will step in and help you...
