Quizplus · Accepted Answer

The specific heat capacity of water is 1 calorie/gram Celsius. To raise 1 gram of water from 100 to 101 degrees Celsius, we need 1 calorie per gram Celsius x 1 gram x 1 degree Celsius = 1 calorie. However, note that the question asked for the specific increase in temperature from 100-101 degrees Celsius, not from 0-100 degrees Celsius. Therefore, we can rule out options B and D. The correct answer is C, which is the energy required to raise the temperature of 1 gram of water by 1 degree Celsius, also known as the calorie.
