Part A) A volume of 80.0 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 21.50 ∘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 and include the appropriate units.
Part B) The specific heat of water is 4.18 J/(g⋅∘C). Calculate the molar heat capacity of water.
Express your answer to three significant figures and include the appropriate units.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
