Answer to Question #143417 in Chemistry for carlitos

Question

Mercury has a specific heat of 0.140 J/g ? 8C. Assume that a thermometer
has 20 (2 significant figures) grams of mercury. How much heat is absorbed by
the mercury when the temperature in the thermometer increases from 98.68F
to 103.28F? (Assume no heat loss to the glass of the thermometer.)

Answer 1

Q=C x m x deltaT

deltaT=103.28-98.68=4.6 F=4.6°C

Q(Hg)=0.140 x 20 х 4.6 = 12.88 J
