6.2 x 10^8 J 6.3 x 10^8 J 7.7 x 10^8 J 7.9 x 10^8 J
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: A recycling plant manager needs to melt 1500 kg of scrap copper to sell to a wire manufacturer. The copper is at 15°C and its melting point is 1083°C. The copper has a specific heat of 385 J/kg x K. How much heat is required to raise the temperature of the copper to its melting point?
Possibilities:
- 6.2 x 10^8 J
- 6.3 x 10^8 J
- 7.7 x 10^8 J
- 7.9 x 10^8 J

6.2 x 10^8 J
