The si unit for energy is the joule (j). sam wants to convert 338.25 j into kj. which operation should he choose? he should multiply 338.25 by 10. he should multiply 338.25 by 100. he should divide 338.25 by 100. he should divide 338.25 by 1000

Answer is (4) - He should divide 338.25 by 1000.

Explanation;

Kilo (k) means 1000 particles/parts.

Hence,

  1000 J = 1 kJ

Therefore, to convert J into kJ, Sam has to divide the value which is in J by 1000.

Hence,

  338.25 J = (338.25 / 1000) kJ = 0.33825 kJ
