The number of calories required to raise the temperature of 1g of water from 15 to 16?C is called___________?
Correct answer: B. Specific Heat capacity
- A. Specific Heat of Vaporization
- B. Specific Heat capacity
- C. Caloric Heat
- D. Both A and C
Explanation
The heat needed to raise 1 g of water by 1 °C is one calorie, and this illustrates water's specific heat capacity, 1 cal/g°C. Students may choose caloric heat, but that is not the standard name for a substance's heat required per unit mass per degree.

About Biological Importance of Water
Water supports life through its polarity, hydrogen bonding and ability to dissolve ionic and polar substances. Its high specific heat, heat of vaporization, cohesion, adhesion and incompressibility help regulate temperature, transport materials and maintain structure, while hydrolysis and osmosis depend directly on water.
