100 cal of heat will raise the temperature of $25 \mathrm{~g}$ of water by (a) $2500^{\circ} \mathrm{C}$; (b) $4^{\circ} \mathrm{C}$ (c) $2^{\circ} \mathrm{C}$; (d) $1^{\circ} \mathrm{C}$.
Calculate the heat change at $100^{\circ} \mathrm{C}$ for each of the following, and indicate whether heat was absorbed/released: a. calories to condense $10.0 \mathrm{~g}$ of steam b. joules to condense $7.60 \mathrm{~g}$ of steam c. kilocalories to vaporize $44 \mathrm{~g}$ of water d. kilojoules to vaporize $5.00 \mathrm{~kg}$ of water
