(c) heat may have been supplied to it
(d) work may have been done on it
Explanation:
- If an object's temperature increases in a time then two possibilities occur. It may have been supplied with heat, which contributes to a rise of the object's internal energy. This will raise body temperature. Therefore option (C) is correct.
- The second explanation is that certain work may have been performed on it, which again leads to a rise of the body's internal energy. That'll also raise the body's temperature. Therefore option (D) is right.
