The heat content of a system is its potential to store heat potential to release heat potential to exchange heat potential to overcome enthalpy

The correct answer is 'potential to store heat'.

Explanation:

Heat content is the amount of energy stored in the system both kinetic and potential.  Each and every substance stores both energies.

The kinetic energy is due to motion of particles and potential energy is due to chemical or nuclear bond holding the system together.

In thermodynamics it is defined as sum of internal energy and product of pressure and volume.

ΔH = heat content pf enthalpy of the system

PΔV = Work done by the system

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
