Question

How much heat is needed to raise 35 grams of gold from 25.0°C to 35.0°C? (The specific heat of gold is 0.13 J/g°C.)

45.2 J
-55.2 J
54.2 J
25.2 J

Answer 1

45.5J

Step-by-step explanation:

ΔT=10°C

specific heat=0.13J/g°C

mass Au=35g

heat=35g•0.13J/g°C•10°C

heat=45.5J=46J

NOTE:I apply significant figures here for the accuracy of the solution.

please rate it,Thanks.
