An 870-g iron block is heated to 370 C and placed in an insulated container (of negligible heat capacity) containing 41.0g of water at 21.0 C. What is the equilibrium temperature of this system? The average specific heat of iron over this temperature range is 560 J/(kgxK). What is the equilibrium temperature of this system? The average specific heat of iron over this temperature range is 560 J/(kg?K).

Answer #1

Using heat balance eqn

M1cp(tequi- t1)= m1*cp(tequi-t2)

.87*560(tequi-370)= .041*4184*(tequi-21)

Solving we get tequi= 288C
