Question

"A fellow student obtained the following data for their calorimetry experiment. Calculate the initial temperature of the warm water, based on these data.
Student's Data:
--Mass of two styrofoam cups --> 37.25g
--Mass of two styrofoam cups + cold water --> 68.13g
--Temperature of cold water --> 23.2 "A fellow student obtained the following data for their calorimetry experiment. Calculate the initial temperature of the warm water, based on these data.
Student's Data:
--Mass of two styrofoam cups --> 37.25g
--Mass of two styrofoam cups + cold water --> 68.13g
--Temperature of cold water --> 23.2

Explanation / Answer

MASS OF COLD WATER=68.13-37.25=30.88 g

mass of hot water=21.65 g

30.88*C(45.9-23.2)=21.65*C*(T-45.9)

initial temperature of the warm water,T=78.277 degree C
