Calorimetry: q = m·c·ΔT

Heat, mass, specific heat, temperature change — one equation ties them together: q = m·c·ΔT. These drills give you three and ask for the fourth, drawing each substance's specific heat from a sourced table (water 4.184, aluminum 0.897, and metals down to gold's 0.129 J/g·°C). Type your answer (rounded to three significant figures); if you slip, the drill names the mistake — most often treating every substance like water, or dropping a factor. The arithmetic is machine-checked; the specific heats are sourced and the calorimetry model is disclosed, not proved.

Model: The calorimeter loses no heat to the surroundings — all the heat stays in the sample. The specific heat capacity c is constant over the temperature range and there is no phase change (no melting or boiling). The arithmetic is machine-checked and the answer is reported to 3 significant figures.
