Answer 1

ANSWER

d) kilocalorie

EXPLANATION

One calorie is equivalent to approximately 4.18 Joules, so 1 cal represents a greater amount of heat energy than 1 J.

Then, 1 kilocalorie is equivalent to 1000 calories, so 1 kcal represents a greater amount of heat energy than 1 cal.

Finally, 1 kcal is equivalent to approximately 3.96 BTU, so 1 kcal represents a greater amount of heat energy than 1 BTU.

Hence, of these options, the largest unit of heat energy is kilocalorie.
