Question

A 45.4 grams of a gold metal sample was heated with the amount of energy of 228 J. Which of the following would the most plausible temperature change of the gold sample? The specific heat of gold is 0.131 J/g.oC.


12.8 oC to 38.3 oC

24.4 oC to 81.6 oC

23.8 oC to 62.1 oC

38.3 oC to 52.1 oC
q = mass Au x specific heat Au x delta T.
228 = 45.3 x 0.131 x delta T.
Solve for delta T, the check the answers and see which matches delta.
