  1. 16.1 Internal energy

    1. • understand that internal energy is determined by the state of the system and that it can be expressed as the sum of a random distribution of kinetic and potential energies associated • With the molecules of a system

    2. • relate a rise in temperature of an object to an increase in its internal energy

  2. 16.2 The first law of thermodynamics

    1. 16.2.1W = p∆V for the work done when the volume of a gas changes at constant

      • recall and use W = p∆V for the work done when the volume of a gas changes at constant pressure and understand the difference between the work done by the gas and the work done on the gas

    2. 16.2.2The first law of thermodynamics ∆U = q + W expressed

      • recall and use the first law of thermodynamics ∆U = q + W expressed in terms of the increase in internal energy, the heating of the system (energy transferred to the system by heating) and the work done on the system
