MC08 ourses Specific Heat C)4 of5 e Home Constants 1 Petlodic Table Part A The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which A volume of 90.0 mL of H20 is initially at room temperature (2200 C) A chilled steel rod at 2.00 Cis placed in the water If the final temperature of the system is 21.50 °C,what is the mass of the steel bar 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 Use the following values Area specific heat of water 4.18 J/(eC) specific heat of steel 0 452 J/C) Note the diference between the terms molar heat e Materials capacity, which has units of J/(mol.°C), and Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

mass of water = 90 g

specific heat = 4.184 J / goc

temperature = 22.00 oC

temperature of steel = 2.00 oC

final temperature = 21.50 oC

heat loss by water = heat gain by steel rod

(m Cp dT)water = (m Cp dT)steel

90 x 4.184 x (22 - 21.50) = m x 0.452 x (21.50 - 2)

m = 21.34 g

mass of steel = 21.3 g
