QuestionA nickel absorbs $74 \mathrm{~J}$ from water cooling from $65.5^{\circ} \mathrm{C}$ to $63.4^{\circ} \mathrm{C}$. Find mass of water: $$\mathrm{C}_{\mathrm{H}_{2} \mathrm{O}}=4.18 \frac{\mathrm{J}}{\mathrm{g} \cdot{ }^{\circ} \mathrm{C}}, \mathrm{~m}_{\mathrm{H}_{2} \mathrm{O}}=[?] \mathrm{g}$$
