Question

select all the correct answers. a worker is holding a filled gas cylinder still. which two sentences are true about the energy of the filled gas cylinder? it has no energy because its being held still. it has gravitational potential energy because of its height. its atoms and molecules have thermal energy. it has motion energy because it will fall if let go. its kinetic energy is being converted to potential energy.

Explanation:

Step1: Analyze energy concepts

Energy exists in different forms. A still - held object can have potential energy.

Step2: Evaluate gravitational potential energy

The gas cylinder held at a height has gravitational potential energy due to its position in the gravitational field.

Step3: Evaluate thermal energy

Atoms and molecules in the gas have thermal energy due to their random motion.

Step4: Analyze kinetic - potential energy conversion

There is no motion currently, so no conversion from kinetic to potential energy. And it has energy (gravitational potential and thermal), so the statement of having no energy is false.

Answer:

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