Mrs. Franklin decides to use her new aluminum pan to scramble eggs. She wants to determine how much heat energy will be needed to
heat her aluminum pan from 20 degrees celsius to 220 degrees celsius. She obtains the specific heat of aluminum from the reference
table. It lists the specific heat of aluminum as 0.90 N/kg*degrees celsius. The pan has a mass of 0.5 kg. She does the calculation
correctly. Which one of the following is her answer?
Your
0.45 joules of heat energy
O 0.9 kilojoules of heat energy
O 90 kilojoules of heat energy
180 joules of heat energy
