2.5 2 1.5 1 0.5 Temperature (deg C) 0 -0.5 -1 -1.5 -2 1 CO -2.5 0 2 3 4 5 Time (min) Graph 1. Freezing point of pure solvent

As you can see in the graph above, the extrapolation of graph on Y-axis yields a freezing point of 0.4 oC. The dip in the temperature below the extrapolation line is known as super cooling.

So, the freezing point of the pure solvent is 0.4 oC.

    Long paths we show that for every n ≥ 3 if deg(v) ≥ n/2 for every v ∈ V then the graph contains a simple cycle (no vertex appears twice) that contains all vertices. Such a path is called an Hamiltonian path. From now on we assume that deg(v) ≥ n/2 for every v. 1. Show that the graph is connected (namely the distance between every two vertices is finite) 2. Consider the longest simple path x0, x1, . ....
