Answer:
I would say A, Gravity can help erosion to occur.
Explanation:
While B,C,D do help cause erosion, that isn't the only way erosion can occur.
The heat lost by the metal should be equal to the heat
gained by the water. We know that the heat capacity of water is simply 4.186 J
/ g °C. Therefore:
100 g * 4.186 J / g °C * (31°C – 25.1°C) = 28.2 g * Cp *
(95.2°C - 31°C)
<span>Cp = 1.36 J / g °C</span>
