multiple choice question
a calorie is the amount of heat that will raise the temperature of how much water 1 degree celsius?

○ 1 gallon
○ 1 liter
○ 1 gram

Explanation:

The definition of a calorie (or gram - calorie) is the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius. A gallon and a liter are larger volume units, and the calorie definition is based on the mass of water (1 gram) rather than these larger volume measures.
