Question

Part A

It takes 55.0 J to raise the temperature of an 9.00 g piece of unknown metal from 13.0C to 24.9 C. What is the specific heat for the metal? Express your answer with the appropriate units.

Cs =

Parts B and C The next two questions pertain to silver. They have nothing to do with unknown metal described in Part A.

Part B

The molar heat capacity of silver is 25.35 J/molC. How much energy would it take to raise the temperature of 9.00 g of silver by 10.1 C? Express your answer with the appropriate units.

q =

Part C What is the specific heat of silver? Express your answer with the appropriate units.

Explanation / Answer

Part A

It takes 55.0 J to raise the temperature of an 9.00 g piece of unknown metal from 13.0C to 24.9 C. What is the specific heat for the metal? Express your answer with the appropriate units.

Q = m*Cp(Tf-Ti)

55 = 9*Cp(24.9-13)

Cp = (55/9)/(24.9-13) = 0.5135 J/gC
