Consider a disordered system made up of a two-dimensional square lattice of particles, where each particle can be in one of two states (up or down). Using the Ising model, calculate the critical temperature at which the system transitions from a disordered state to an ordered state. How does the critical temperature change as the disorder in the system increases (i.e. as more particles are in a random state)?
