Answer 1

Answer:

4.11x10⁶Joules

10.04Cal

Explanation:

Calories and joules are units of energy used in several fields of science.

4184Joules are equal to 1 Cal.

In joules, 982 calories are:

982 Calories * (4184 J / 1 Cal) =

4.11x10⁶Joules

In the same way, 4.2x10⁴ Joules are:

4.2x10⁴J * ( 1Cal / 4184J) =

10.04Cal
