Question

Which statement accurately describes a type of potential energy found in a container full of a chemical substance in liquid form? (1 point)

The bonds between atoms are one place where potential energy is stored.

The vibration of the atoms in molecules is one place where potential energy is stored.

The rotation of the particles is one place where potential energy is stored.

The speed of the particles is one place where potential energy is stored.

Answer 1

The statement that accurately describes a type of potential energy found in a container full of a chemical substance in liquid form is the bonds between atoms are one place where potential energy is stored.

• The energy that is stored in chemical bonds (between two atoms) is a form of potential energy.
• The vibrations of the atoms are because of the thermal energy.
• The rotation of the particles shows rotational kinetic energy.
• The speed of the particles represents the translational kinetic energy of these particles.
• A molecule can have all the forms of energy together. The sum of these shows the total energy stored in a molecule.

Answer 2

Option B is the right answer.

• When liquids are placed inside a container, the energy stored within them is potential energy as it is not moving to have kinetic energy.

• These molecules of the liquid are stationary and therefore the vibrations of the atoms are in one place.

• Unlike gaseous molecules whose speed is high, the water molecule's speed is said to be low when compared to gaseous molecules.

• This is because the water molecules contain intermolecular hydrogen bonds that keep the molecules intact and at the same time exhibits liquid properties.

• This is the reason for the vibration of atoms remains the same.
