Raising the temperature of 10.0 g of water from 10.0 °C to 20.0 °C requires 100.0 cal of energy, while raising the temperature of 10.0 g of aluminum from 10.0 °C to 20.0 °C requires 22 cal. More calories are required to heat the water because
A)water is a liquid and aluminum is a solid at 10.0 °C.
B)ten grams of water occupies a larger volume than 10.0 g of aluminum.
C)water has a greater potential energy than aluminum.
D)water has a larger specific heat than aluminum.
E)10.0 °C is closer to the melting point of water than to the melting point of aluminum.

Question

Quizplus · Accepted Answer

Specific heat is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. Water has a higher specific heat than aluminum, which means it requires more energy per gram to raise its temperature. Therefore, more calories are required to heat the water from 10.0°C to 20.0°C than to heat the aluminum from 10.0°C to 20.0°C.
