Weathering because it's "wearing" down something to make sediment
Answer:
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
Explanation
Energy can be calculated by the equation
Q = m x Cp x delta T
where
m = mass = 0.5 kg
Cp = specific heat of water = 4184 J
Delta T = 12 degrees
Multiplying all
Q = 0.5 x 4184 x 12 = 25104 Joules
Converting it to Calories
Q = 25104 / 4.184 = 6000 Calories or 6 Kcal
