    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.

    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.
