Solve for k:
ln(y) = ln(a) + k * ln(x)
ln(0.666) = ln(a) + k * ln(0.05)
ln(0.95) = ln(a) + k * ln(0.5)
ln(a) = ln(0.95) k * ln(0.5)
ln(0.666) = ln(0.95) k *

Homework 1 1. A cube of ice having temperature Tice<273K is placed into the lake with Tlake>273K. Calculate the change in the entropy of the cube-lake system as it comes to the thermal equilibrium. Assume the specific heat of ice Cice, the water Cw and th
Problem I (10 points)
Consider a system of N distinguishable particles. Each particle can occupy only one of the two levels 1 or 2, where 1< 2. Assume N is very large. You can distribute the particles in such way that n particles reside on level 2 while N
