Gases

A force is applied to a container, reducing its volume by half. The temperature increases (because the force did work on the container).

How can this be reconciled with Charles law?

Seems like the temperature would decrease, given Charles law

Any ideas? I'm sure there is a simple reason, like charles law only applies to ideal gases or something?

Charles' law only applies to gasses with constant pressure and moles. Since you are increasing the pressure, Charles' law does not apply.

This can also be reasoned through the ideal gas law: PV=nrT
While V is directly proportional to T; for V/T to = some constant, both P and n must be constant.
