Answer

Answer:

B. It has gravitational potential energy because of its height., C. Its atoms and molecules have thermal energy.

Explanation:

Step1: Analyze gravitational potential energy

The cylinder is at a height above the ground while being held. Gravitational potential energy is given by $U = mgh$ (where $m$ is mass, $g$ is gravitational - acceleration, and $h$ is height). So it has gravitational potential energy.

Step2: Analyze thermal energy

Atoms and molecules in any object at non - absolute zero temperature have thermal energy due to their random motion. The gas in the cylinder is no exception.

Step3: Analyze other options

The cylinder is not in motion currently so it has no motion (kinetic) energy at the moment, so option D is wrong. Also, since it is not moving, there is no conversion of kinetic to potential energy, so option E is wrong. And it has energy (gravitational potential and thermal), so option A is wrong.
