Part B
The amount of boiling water required to raise the temperature of25.0 kgof water in the bath to body temperature is 4.80 kg.
In this process, the heat lost by the boiling water is equal tothe heat gained by the room-temperature water. How much heat wastransferred in this process?
Express your answer to four significant figures andinclude the appropriate units.
n this problem answers are requested to three significantdigits for grading purposes. The true number of significant digitsmay be more or less.
Part A
A volume of 95.0 mL of H2O is initially at room temperature(22.00 ?C). A chilled steel rod at 2.00 ?C is placed in the water.If the final temperature of the system is 21.50Â Â ?C ,what is the mass of the steel bar?
Use the following values:
specific heat of water = 4.18 J/(g??C)
specific heat of steel = 0.452 J/(g??C)
Express your answer to three significant figures andinclude the appropriate units. mass of the steel =
