Transcribed Image Text:1. Consider a situation where two volumes of water, one hot, one cold, are both added to a foam
cup.
(a) Sketch a diagram for the cup and volumes of water, using a dashed line to separate the
two volumes, and label all the components.
(b) To your sketch, add a line and label it to indicate the heat flow in this system. For now,
asssume the foam is a perfect insulator.
(c) Write the mathematical relationship between the heat flows for the hot and cold water,
qhot and qcold based on you diagram from parts (a) and (b).
(d) Once the water is well-mixed, both volumes of water come to the same temperature Ts.
Write the mathematical expressions for the temperature changes for each of the volumes
of water, ATcold and AThot, assuming they started at Tcold and Thot for the cold and hot
water respectively.
(e) Assuming that the foam undergoes the same temperature change as the cold water (it's
no longer a perfect insulator!), write a modified version of your equation from part (c)
that relates the heat flows for the hot and cold water and the foam cup, qhot, Acold, and
9foam:
(f) Re-write your equation from part (e) replacing each of the heat flows with the appro-
priate masses mcold and mhot, heat capacities Cp, H,0
temperature changes Tcold and Thot.
and Ccup
= mcup X CP, foam, and
