In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
