question

Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate ΔH\Delta H when two copper blocks, each of mass $10.0 \mathrm{~kg}$, one at 100∘C100^{\circ} \mathrm{C} and the other at 0∘C0^{\circ} \mathrm{C}, are placed in contact in an isolated container. The specific heat capacity of copper is $0.385 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~g}^{-1}$ and may be assumed constant over the temperature range involved.
Plain-text mathematical notation (without MathML)
Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate ΔH when two copper blocks, each of mass $10.0 \mathrm{~kg}$, one at 100^(∘)C and the other at 0^(∘)C, are placed in contact in an isolated container. The specific heat capacity of copper is $0.385 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~g}^{-1}$ and may be assumed constant over the temperature range involved.

Assume that all gases are perfect and that data refer to 298.15 K unless otherwise stated. Calculate $\Delta H$ when two copper blocks, each of mass $10.0 \mathrm{~kg}$, one at $100^{\circ} \mathrm{C}$ and the other at $0^{\circ} \mathrm{C}$, are placed in contact in an isolated container. The specific heat capacity of copper is $0.385 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~g}^{-1}$ and may be assumed constant over the temperature range involved.
