Aworker is holding a filled gas cylinder still. which two sentences are true about the energy of the filled gas cylinder?

a .it has no energy because it’s being held still.

b .it has gravitational potential energy because of its height.

c .its atoms and molecules have thermal energy.

d .it has motion energy because it will fall if let go.

e .its kinetic energy is being converted to potential energy.

it can be more than one 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

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.
