what type of energy transfer occurs as a coiled spring is released
Answer:
When a spring is coiled up or a rubber band is stretched, mechanical energy is stored in it. When the spring uncoils or the rubber band snaps back, this energy is released. This stored mechanical energy is called potential energy because it has the potential to make things happen.Explanation:

[WILL MARK BRAINLIEST!!] Describe the relationship between molecular structure and the strength of electrostatic
forces between molecules. How does this impact boiling and melting points?
Answer:
increase the bonding strength between two or more molecules
hope this help
Explanation:
Boiling points and melting points
The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces.

The electron configuration of element Y ends in s?p4. What is
the symbol for the ion most commonly formed by this element?
a y2+
b y2-
с ү6+
d Y
This problem is providing us with the end of the electron configuration an element as s²p⁴ and asks for the most commonly formed ion. At the end, the answer is b Y²⁻.
Electron configurationIn chemistry, when analyzing electron configurations, one must first take into account how the energy levels must be filled with electrons.
Now, note the problem states that the electron configuration ends by s²p⁴, which means it is closer to complete the octet so it needs two electrons in order to do so, as it behaves as a nonmetal.
Therefore, the most commonly ion formed by this element is Y²⁻, because of the fact that it needs two electrons to complete the octet and thus become chemically stable and likely to bond with a metal.

According to the Law of Conservation of Matter, what happens to atoms of gas in a balloon when it is placed in the freezer?
the number of atoms stays the same and the energy stays the same, keeping the volume the same
the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume
the number of atoms increases, causing an increase in energy and an increase in volume
the number of atoms decreases, which takes up less space and decreases the volume
Answer:
the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume
Explanation:
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.
