Question

Cooper metal has a specific heat of 390 j/kg C. Calculate the amount of heat required to raise the temperature of 22.8 g of copper to 875 C

Answer 1

Answer:

= 7,600 Joules

Explanation:

Heat required to raise the temperature of a material is given by the formula;

Heat = mass × specific heat capacity × change in temperature.

In this case;

mass =22.8 g or 0.0228 kg

specific heat capacity = 390 J/kg°C

Temperature change = 875°C - 20°C = 855 °C

Therefore;

Heat = 0.0228 kg × 390 ×855

        = 7,602.66 Joules

        = 7,600 Joules
