Physics for IGCSE & O level - Thermal Effects (Section 8 - No. 1)
If a 2 kg block of copper is heated to 50°C, how much energy will it need if its specific heat capacity is 385 J/kg°C?
38500 J
385 J
19250 J
7700 J
Explicaţie
Energy transferred = mass x specific heat capacity x temperature change. 2 * 385 * 10 = 7700 J
