The thermodynamic properties of various phases of tin are calculated employing the method of adiabatic switching with modified embedded atom method (MEAM) potentials. The experimental $\alpha \to \beta$ and $\beta \to \mathrm{liquid}$ transition temperatures are reproduced within an 11% accuracy. Good agreement with experiments is also obtained for other thermodynamic quantities. We demonstrate the versatility and accuracy of MEAM by how well it reproduces both metallic and covalent phases of tin over a wide temperature range and over a wide range of densities.
