B) 1500 calories.
C) 2000 calories.
D) 2400 calories.

Answer 1

Answer:i think it is c

Answer 2

C. 2000 calories.

Explanation/calculation:

Specific heat capacity = calories / mass * (final temperature - initial temperature)

1 = calories / 100 * (60 - 40)
1 = calories / 100 * 20
1 * (100 * 20) = calories
1 * 2000 = calories
2000 = calories
