One calorie is the heat needed to warm 1 g of water from
A14.5 °C to 15.5 °C
B99 °C to 100 °C
C3.5 °C to 4.5 °C
D0 °C to 1 °C
Answer & Solution
Correct answer: A. 14.5 °C to 15.5 °C
Because the specific heat of water varies with temperature, the calorie is fixed for the 14.5 °C to 15.5 °C interval.
