Question

A 446-g piece of copper tubing is heated to 89.5 d 6Q11

Answer 1

Answer #1

Heat lost by tubing=Heat gained by water+vessel

446×0.387×(89.5-T)=159×1×(T-22.5)+10×(T-22.5)

15447.8-172.6T=169T-3802.5

T=56.35°C(approx).

I am currently working 6.45. I had the equation set up corrctly until i got to the circled portion of the second picture. I dont understand why they multiplied the (10J/C) by (Tfinal - 22.8C) when i already had (Tfinal -22.8C) in the equation right before that. I hope that makes sense.
