Problem $4$

While making dinner, a hot glass dish with mass $1\mathrm{.}50$ kg is placed onto a wooden cutting board with mass $5\mathrm{.}00$ kg$.$ At first, the dish is $150$C and the block is $20$C$.$ Eventually, the two items become the same temperature. We$$ll assume that no heat is lost, meaning that all of the heat that leaves the dish goes into the block. What temperature do the two objects come to$?$ College Physics by Urone and Hinrichs says that the specific heat of glass is $840$ J$/($kg $$ K$)$ and the specific heat of wood is $1700$ J$/($kg $$ K$).$

Problem $5$

Also while making dinner, some ice is used to cool off some food. The $0\mathrm{.}200$ kg of ice starts at $0$C$,$ melts, and then warms up to $20\mathrm{.}0$C$.$ How much heat did the ice take in$?$ College Physics by Urone and Hinrichs says that the specific heat of water is $4186$ J$/($kg $$ C$),$ and the latent heat of water is $3\mathrm{.}34105$ J$/$kg$.$
