In an Experiment, 25 $\degree$ C and Then Quickly Transferred to 100

question 4

Multiple Choice

In an experiment, 25.00 g of iron is heated to 228.00 $\degree$ C and then quickly transferred to 100.0 g of water in a calorimeter at 18.00 $\degree$ C.The final temperature comes to 20.50 $\degree$ C.What is the approximate heat capacity of the calorimeter? [c_p(iron) = 0.450 J/(g . $\degree$ C) ; c_p(water) = 4.184 J/(g . $\degree$ C) ]

• A)6.21 J/\(\degree\)C
• B)16.3 J/\(\degree\)C
• C)515 J/\(\degree\)C
• D)934 J/\(\degree\)C
• E)1350 J/\(\degree\)C
