Suppose that there are n=108 two-state systems, each with energy difference e=6 × 10-21 j between the two states. the environment temperature is 300 k. the number of systems in their high energy states is m. therefore, the free energy is a function of m: f(m).what is du/dm?

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
