A 2.00-kg metal object requires 1.00 × 104 J of heat to raise its temperature from 20.0 °C to 60.0 °C. What is the specific heat of the metal?

Answer:

  0.125 J/(g·k)

Explanation:

Specific heat has units of J/(g·K), so we find the value by dividing the energy by the product of mass and temperature change.

  (10^4 J)/(2·10^3 g·(60 -20)K) = 10/(2·40) J/(g·K) = 0.125 J/(g·k)
