The specific heat of copper is 0.385 J g^-1 K^-1. If 34.2 g of copper, initially at 21.0 °C, absorbs 4.689 kJ, what will be the final temperature of the copper?

Question

To find the final temperature, use the formula q = mcΔT. Here, q = 4689 J, m = 34.2 g, c = 0.385 J/g°C. Solving for ΔT gives ΔT = q/(mc) = 4689/(34.2*0.385) = 356°C. Adding the initial temperature (21°C) gives a final temperature of 377°C.
