a .250kg block of aluminum is heated to 100 C and then dropped into .60 kg of water that is initially at 20C. What is the equilibrium temperature of the system? The specific heat of aluminum is .22 kcal/kg C

Answer 1

The sum of the heats gained is zero.

heatgainedAl+heatgainedWater=0
.250*.22*(Tf-00)+.6*c*(Tf-20)=0
solve for Tf

Answer 2

thanks!
