Q:
# 4. The specific heat of aluminum is 0.902 J/g. If a metal smith has 300g of aluminum and wants to melt it down to make a lock. He increases the temperature from 20 to 200. How much heat does he need to apply?

Accepted Solution

A:

Answer:Q = 48708 JStep-by-step explanation:Q = mcΔtQ = 300 g x (0.902 J/g°C ) x (200°C - 20°C)Q = 300 g x (0.902 J/g°C ) x (180°C)Q = 48708 J
