Answer 2

Explanation:

True statement:- 1 J = 0.239 calorie (to three significant figures).

The conversion factor between joules and calories is derived from the definition of the calorie and the conversion factor between the Celsius and Kelvin temperature scales. One calorie is equal to 4.184 joules, or approximately 4.2 joules. Therefore, the correct statement is "1 calorie = 4.184 J" or "1 J = 0.239 calorie".
