Answer: 5040 joules

Explanation:

How much energy is released when 150g of silver cools from 220°C to 80°C?

Given the following :

Mass (m) of silver = 150g

Change in temperature (ΔT) = (220 - 80)°C = 140°C

Q=mcΔT

Where Q = quantity of heat

m = mass of silver ; c = specific heat capacity

Specific heat capacity of silver = 0.240 j/g°C

Q = (150 * 0.240 * 140)

Q = 5040J
