A 50kg object on earth weighs 81.67 on the moon
Answer:
Correct option: C -> 7.4 kcal
Explanation:
First we need to find the energy necessary to heat the silver from 20°C to 961°. The change in temperature is 961 - 20 = 941, so the energy necessary is:
941 * 0.056 * 100 = 5269.6 cal
Then, for the melting process, we will need:
21 * 100 = 2100 cal
So the total energy needed is:
5269.6 + 2100 = 7369.6 cal = 7.4 kcal
Correct option: C
No. Science is all about facts and experiments. Making stuff up would go against that, and wouldn't be science.
