An ice cube melts at room temp. What are the thermo properties of this process?

The system (the water in the ice cube) increases in entropy (S), free energy (G) decreases, and heat is required, so H is positive. So, S= positive, H= positive, and G= negative. I'm not entirely sure on the free energy part, but reactions with negative values for G are spontaneous, and the melting of an ice cube is spontaneous, so it follows that G would be negative.
