Answer:
5250 Joules
Explanation:
Mass = 50g
Initial Temperature = 125.0 degrees Celsius
Final Temperature = 100 degrees Celsius
Temperature change = Final - Initial = 100 - 125 = -25
Heat = ?
These quantities are related by the equation;
H = mCΔT
where c = specific hear capacity = 4.2 J/g°C
H = 50 * 4.2 * (-25)
H = -5250 J (The negative sign is because heat is being released)
