Question

A worker is holding a filled gas cylinder still. Which two sentences are true about the energy of the filled gas cylinder?
1. It has no energy because it’s being held still.
2. It has gravitational potential energy because of its height.
3. Its atoms and molecules have thermal energy.
4. It has motion energy because it will fall if let go.
5. Its kinetic energy is being converted to potential energy.
*Multiple choice*

Answer 1

1 is wrong because being held still it possesses potential energy. 4 and 5 is also wrong. So your correct answer is 1 and 2

Answer 2

Answer:

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

3. its atoms and molecules have thermal energy.

Explanation:

It is held motionless, thus it has no energy. Due of its height, it contains gravitational potential energy.

A doubling in height will lead to a doubling in gravitational potential energy since an object's gravitational potential energy is directly proportionate to its height above the zero point. The gravitational potential energy will triple with a tripling of height.

its atoms and molecules have thermal energy.

due to gas inside the cylinder its molecules and atoms will contain some thermal energy.
