What the heck is isometric heating?

Isometric just means that the volume doesn't change.

When you heat something, the volume always changes, the vibrating molecules, thus changing the density.

Not necessarily. If a gas is contained in a rigid tank its volume can't change. Heating will cause the pressure to increase instead.

The more familiar term is:"isochore heating".It specifies it requires constant volume.While "isometric" can mean the same thing,bu u neet to analyze its origin:"isos"(Ancient Greek):the same;"metric<metron"(Ancient Greek)=to measure.

Don't store your tanks in the sun.

Ooops... I just found out I wanted to know what isobaric heating is, sorry.

Well,that's something else.It assumes that a gas (actually works with a solid as well) is heated (its temperature is rising) and it dilatates at the same time,while the pressure is kept constant.For a solid it works wonderfully.

Isos-the same;baros-pressure.

Isobaric means that the pressure is constant. When it's beeing heatet the volume changes. An exampel of this is a heath resorver with a movable cylinder, hich is being haetet.
