Difference between Coop Up and Incoercible

COOP UP vs INCOERCIBLE: ADJECTIVE

That cannot be confined in, or excluded from, vessels, like ordinary fluids, gases, etc.; said of heat, light, electricity, etc.
Not capable of being reduced to liquid form by pressure.
That can note be confined in, or excluded from, vessels, like ordinary fluids, gases, etc.; -- said of the imponderable fluids, heat, light, electricity, etc.
Not capable of being reduced to the form of a liquid by pressure; -- said of any gas above its critical temperature.
Not to be coerced; incapable of being compelled or forced.
Difficult or impossible to coerce or control forcibly.

In physics, incapable of being reduced to a liquid form by any amount of pressure. Certain gases were formerly supposed to have this property. See gas.
Not to be coerced or compelled; incapable of being constrained or forced.
Incapable of reduction to tangible condition by pressure: applied to forms of energy, such as heat and electricity, when they were thought of as extremely subtile fluids.
