In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. 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 21.30 °C, what is the mass of the steel bar? Note the difference between the terms molar heat Use the following values: capacity, which has units of J/(mol °C), and specific heat, which has units of J/(g. °C). 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. > View Available Hint(s) HẢ mass of the steel = Value Units Submit Part B The specific heat of water is 4.18 J/(g . °C).
