Physics · Secondary 3 · Hard · Specific heat capacity

A 0.80 kg block of metal at 90 °C is placed into 0.40 kg of water at 20 °C in an insulated container. The final temperature of the mixture is 30 °C. Take the specific heat capacity of water as

4200\,\text{J kg}^{-1}\,\text{K}^{-1}

.

What is the specific heat capacity of the metal?

350 J kg⁻¹ K⁻¹
700 J kg⁻¹ K⁻¹
2100 J kg⁻¹ K⁻¹
4200 J kg⁻¹ K⁻¹
