1. Explain how energy can move spontaneously from a system of low total energy to a system of higher total energy.

2. Why is it more common to think of temperature as being related to the rate of change of energy with respect to entropy than it is to think of it as being related to the rate of change of entropy with respect to energy?

Suppose we start out in a configuration with 6 total packets of energy, with 4 in subsystem A and 2 in subsystem B. If one packet of energy moves from A to B (so that we end up with 3 packets in each subsystem), calculate (in terms of kB) 1. the change in entropy of subsystem A, ∆SA 2. the change in entropy of subsystem B, ∆SB 3. the change in entropy of the whole system, ∆SAB

please explain why!! 1. An electron is released from rest in a region of space with a nonzero electric field. As the electron moves, does the electric potential energy of the system increase or decrease? Explain. 2. An electron is released from rest in a region of space with a nonzero electric field. As the electron moves, does the electron move from a position of high to low electric potential? Explain.

The equilibrium constant of a system, K, can be related to the standard free energy change, ΔG∘, using the following equation: ΔG∘=−RTlnK where T is a specified temperature in kelvins (usually 298 K) and R is equal to 8.314 J/(K⋅mol). Under conditions other than standard state, the following equation applies: ΔG=ΔG∘+RTlnQ In this equation, Q is the reaction quotient and is defined the same manner as K except that the concentrations or pressures used are not necessarily the equilibrium values....
