Answer:

B .It has gravitational potential energy because of its height.

C .Its atoms and molecules have thermal energy.

Explanation:

B. The cylinder has gravitational potential energy; in fact, this is given by

[tex]GPE=mgh[/tex]

where m is the mass of the cylinder, g is the gravitational acceleration and h is the heigth of the cylinder above the ground. Since the height h is different from zero, it means that the GPE is different from zero.

C. The gas inside the cylinder has thermal energy, because its atoms and molecules constantly move (they have a random motion called Brownian motion), and this kind of energy due to the motion of molecules is called thermal energy.

A still holding gas cylinder above the ground has gravitational potential energy and thermal energy.

What is Potential energy?

The energy of an object or system is due to its position. For example- Here cylinder has some energy because it is positioned at some height above the ground.

Thermal energy:

The energy of a system is due to the motion of its particles. For example- the gas particles inside the cylinder are randomly moving.  

Therefore, a still holding gas cylinder above the ground has gravitational potential energy and thermal energy.
