Make a graph that shows how the temperature of the mixture depends on the number of cups of hot water in the mixture. blank graph paper

 

According to your graph, how much hot and cold water would be needed to produce a mixture at 27 C?

If you mix equal volumes of hot and cold water (any volume), what would you expect the resulting temperature to be?
