What are the interacting systems in this problem? On a hot summer day, you decide to make some iced tea. First, you brew $1\mathrm{.}50$ LL of hot tea and leave it to steep until it has reached a temperature of TteaTtea $=75\mathrm{.}0$C$$C$.$ You then add $0\mathrm{.}975$ kgkg of ice taken from the freezer at a temperature of TiceTice $=0$C n expression for conservation of energy by considering the heat lost or gained by the tea and ice. This expression will help you solve for the final temperature of the system

Start by identifying the interacting systems and how they change. Then list the known and unknown quantitie You decide to make several more batches of iced tea. The conditions under which you make these batches are identical except that for each batch one initial condition is varied. Determine the impact that each of these changes will have on the final temperature of the iced tea.
