Abstract
Computer simulations are reviewed in the study of molecular liquids and solutions. The characteristics in the computer simulations, and what is expected from the computer simulations in the study of the thermal propeties of substances are summarized from the stand point of the experimentalists who want to study the microscopic aspects also. Three examples are described: the calculation of the free energy of liquids/solutions, the derivation of the equation of state of liquid water, and the calculation of the transport properties of liquid water by the computer simulations.
