Increase in entropy

  1. Oct 12, 2009 #1
    2.1 x107 kg of ice and snow at 265 K slides 0.55 km (vertical distance) down a mountain in an avalanche. What is the increase in entropy? I am having trouble finding an equation on how to solve this problem. If anyone could help me at all, thank you.

    Change in entropy dS = dQ/T.
    Here dQ = dW = mgh.
