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 22.0 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

The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of substance by 1 degree Celsius. Water has a larger specific heat than aluminum, meaning that it requires more energy to raise the temperature of water than the same mass of aluminum. Therefore, more calories are required to heat the water in this scenario.
