The specific heat of copper is 0.385 J/(g ∙ °C).If 34.2 g of copper,initially at 25.0°C,absorbs 4.689 kJ,what will be the final temperature of the copper?
A) 25.4°C
B) 27.8°C
C) 356°C
D) 381°C

To find the final temperature, use the formula q = mcΔT, where q is the heat absorbed (4689 J), m is the mass (34.2 g), c is the specific heat (0.385 J/g°C), and ΔT is the change in temperature. Solving for ΔT gives ΔT = q / (mc) = 4689 / (34.2 * 0.385) = 356°C. Adding the initial temperature (25°C) gives a final temperature of 381°C.
