The phrase "ability to do work" is best defined by the concept of energy. Energy is the capacity to do work, and work is defined as the exertion of force over a distance. Calorie is a unit of energy, but it specifically refers to the amount of energy needed to raise the temperature of one gram of water by one degree Celsius.
