The thermodynamics of the DNA helix‐coil transition is studied, starting from the thermodynamical potential difference between the states helix and coil; this potential difference is understood as the difference in free energies. With only three parameters obtained from experimental data different quantities of the T 2 phage DNA molecule are calculated. It is observed that the phase transition is of second order.
