A student is selecting a material to be used as an
insulating material. The data below shows data from an
investigation about glass. Water at 50 degrees Celsius
was placed in a glass vessel and the temperature was
measured every 5 minutes.
Specific heat of glass: 753 J/Kg
Time for water to reach 25 degrees Celsius: 20 minutes
What material would be the best selection for an
insulating material, and what would the effect be on the
time for water to reach 25 degrees Celsius?
Copper: 385 J/Kg
Aluminum: 898 J/Kg
