Answer:

Q = 197505J

Step-by-step explanation:

Mass (m) = 825g

Specific heat capacity (c) = 1.8J/g°C

Initial temperature (T1) = 22°C

Final temperature (T2) = 155°C

Heat energy (Q) = ?

Q = mc∇t

Q = mc(T2 - T1)

Q = 825 * 1.8 * (155 - 22)

Q = 1485 * 133

Q = 197505J

The heat energy required to raise it through that temperature is 197505J
