Are perpetual motion machines possible?
A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can...

The World If... electricity was free
Imagine a world in which electricity was free. Heating and powering homes for nothing would bring obvious benefits, but there would be downsides too.

Free Energy of Dissolution
We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

Practice Problem: Cell Potential, Equilibrium Constants, and Free Energy Change
Mercy me, how are cell potential, equilibrium constants, and free energy change all related? By a few different equations, that's how. See if you can solve for these values given some data!

Practice Problem: Free Energy and Nonstandard Conditions
We know that a lot of thermodynamic data is collected under standard conditions, but sometimes we will want to assess the free energy change associated with a process that is not occurring under standard conditions. Any other conditions...

Practice Problem: Calculating Free Energy Change
We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...
