Skills Check - Energy is Measurable
Name_______________
1. A block of aluminum weighing 140g is cooled from 98.4°C to 62.2°C with the release of 1080
joules of heat.
a. From this data,calculate the specific heat of aluminum
b. Why will an iron pan heat up more quickly than water when exposed to the same amount
of energy?
c.
In our food calorimetry lab, how did the amount of food we burned affect the
amount of heat that was transferred to the water?
i.
How does this relate to chemical bond energy?
2. a. ​How much energy does it take to melt 45 g of ice at -25 degrees celsius when it is heated to a
gas at 113 degrees celsius?
b. ​Does a transfer of energy always result in a change in temperature? Explain.
