The energy needed to warm something is its mass times its specific heat capacity times the temperature rise. Rearranged, the temperature rise is the energy divided by mass times specific heat capacity. Water has a very high specific heat capacity, so the same energy barely warms it, while a metal like lead races up. Supply enough energy to reach the target temperature rise.
MissionWarm the sample by exactly 25 °C using the heater.Round 1Streak 0Best 0
For the same energy and mass, the hottest is the one with:
specific heat capacity c4200 J/kg°C
temperature rise = Q ÷ (m c)23.8 °C
temperature rise = energy divided by (mass times specific heat capacity).
