Answer 1

To convert 55.3 J to calories, multiply 55.3 by the conversion factor of 0.2390, resulting in 13.2 calories.

Step-by-step explanation:

To express 55.3 J of heat (or energy) in units of calories, we use the conversion factor, where 1 joule is equivalent to 0.2390 calories. Therefore, to convert joules to calories, we multiply the number of joules by 0.2390:

55.3 J × 0.2390 cal/J = 13.2 cal

Thus, 55.3 J of heat is equivalent to 13.2 calories.
