Question

What is the specific heat of metal if its mass is 26.86g and it requires 418.6 J of heat energy to raise its temperature from 27.4 oC to 67.3°C?

Answer 1

The specific heat capacity is 0.364 J·°C⁻¹g⁻¹; q = mcΔT; ΔT = T₂ - T₁ = 67.3 °C - 27.4 °C = 39.9 °C; c =
`(q)/(mDT) = (418.6 \text J)/(28.86 g * 39.9 \text C)` = 0.364 J·°C⁻¹·g⁻¹
