Answer to Question #81074 in General Chemistry for Kathryn Keranen

Question

A sample of packing gel (4.75 g) is heated from 15 to 82 degrees C. Calculate the amount of energy absorbed by the packing gel during this process.

PHYSICAL DATA FOR PACKING GEL: (Hint: not all of this information is needed)

Specific Heat (gaseous packing gel) = 27.8 J/gC

Specific Heat (liquid packing gel) = 17.9 J/gC

Specific Heat (solid packing gel) = 41.1 J/gC

Melting Point Temp = 13 degrees C

Boiling Point Temp = 56 degrees C

Heat of fusion of packing gel = 132 J/g

Heat of vaporization of packing gel = 43 J/g
