Explain two ways object can become electrically charged (not examples)
Final answer:
Objects can be charged by contact, where electrons are transferred through physical touch, or by induction, where a charged object causes an internal rearrangement of charges in a nearby neutral object without touching it.
Explanation:
Objects can become electrically charged in several ways, but two primary methods are charging by contact and charging by induction.
Charging by contact occurs when two objects are physically touched together, transferring electrons from one to the other. If one material holds onto electrons more tightly than the other, it can steal electrons when they are separated. For instance, rubbing your feet on a carpet can transfer electrons to your body, leading to an excess negative charge.
Charging by induction involves bringing a charged object near a neutral object, without physical contact. The presence of the charged object causes electrons within the neutral object to rearrange, producing a region of excess positive charge and a region of excess negative charge. If the object is then separated into two parts during this process, one part can end up with a net positive charge, and the other with a net negative charge.

What can change if a liquid is stirred?
1.attractive forces between molecules
2.chemical bonds between the atoms of the molecules
3.position of the molecules
4.shape of liquid
Stirring a liquid changes the position of the molecules and the shape of the liquid but does not alter the attractive forces between molecules or the chemical bonds within the molecules. Liquids adapt the shape of their container due to cohesive forces, while solids are rigid.
When a liquid is stirred, the outcomes can include the change in the position of the molecules and the shape of the liquid. Stirring a liquid does not affect the attractive forces between molecules on a long-term basis; these forces are part of the liquid's characteristics and would only be temporarily disrupted by motion. Additionally, stirring will not break or form chemical bonds within the molecules, as these interactions occur during chemical reactions and require changes in energy that typically are not provided by simply stirring.
Liquids take the shape of any container they are poured into owing to cohesive forces among their molecules. On the liquid's surface, these forces are unbalanced, promoting a reduction in surface area which is why drops form spherical shapes. In contrast, solids maintain their shape because their molecules are arranged in a fixed, rigid structure held together by stronger intermolecular forces.
All neutral atoms and molecules exert attractive forces on each other, known as van der Waals forces. These include dispersion forces, which increase with molecular size, and can induce dipoles in adjacent atoms; dipole-dipole attractions; and hydrogen bonds, which are strong dipole-dipole interactions involving hydrogen bonded to highly electronegative atoms (F, O, or N).
a) At what time of day is heat flow into the atmosphere (Hin) greatest?
The greatest heat flow into the atmosphere occurs around midday, 1200-1300 hr, when solar radiation and resulting insolation are at their peak.
The greatest heat flow into the atmosphere, or Hin, typically occurs around midday when the sun is highest in the sky, which is approximately 1200-1300 hr. This phenomenon is due to the fact that solar radiation is at its maximum during this time, resulting in the highest rates of insolation or incoming solar radiation.
As the earth absorbs this energy, it heats up and subsequently re-radiates heat back into the atmosphere, thus heating it. The atmosphere maintains this heat due to dry air being athermanous, meaning it allows luminous rays to pass through while retaining darker radiated rays. This process leads to a higher sensible heat transfer in the atmosphere, particularly evident in tropical and subtropical deserts where surface temperatures are highest, facilitating this convective heating of the air.

when you put limp celery stalks in water, they firm up. WHY?
Limp celery stalks firm up in water due to the process of osmosis- water molecules moving into the dehydrated celery cells causing them to become rehydrated and firm.
Explanation:When you place limp celery stalks in water, they firm up due to a process called osmosis. Osmosis is a biological process that involves the movement of water from an area of lower solute concentration (in this case, the water) to an area of higher solute concentration (the limp celery stalk). The cells in the celery stalk are dehydrated, meaning they have a higher solute concentration than the water. When submerged in water, the water molecules naturally flow into the celery's cells, causing them to rehydrate and become firm again.

what two things are components of ribosomes
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. These build large and small subunits that facilitate protein synthesis within cells. Eukaryotic and prokaryotic ribosomes differ slightly in size but share the same basic structure and function.
Components of Ribosomes
The two things that are primary components of ribosomes are ribosomal RNA (rRNA) and proteins. These components come together to form two subunits of the ribosome: the large subunit and the small subunit, necessary for protein synthesis in cells. Eukaryotic ribosomes, found in animal and plant cells, consist of 60S (large subunit) and 40S (small subunit). In contrast, prokaryotic ribosomes, such as those in bacteria, are slightly smaller, with 50S (large subunit) and 30S (small subunit).
Ribosomes function as molecular machines that facilitate the synthesis of proteins, translating mRNA instructions into polypeptide chains. They can be found free floating within the cytoplasm, or bound to structures such as the endoplasmic reticulum (ER) and nuclear envelope in the cell, acting as intercellular protein factories. This machinery is critical for the function of the cell, and by extension, the entire organism.

Which molecular property defines the location of electrons?
The location of electrons in a molecule is defined by the electronic charge density distribution, which influences all molecular properties. Electronegativity affects this distribution, and molecular orbital theory explains bonding and electron arrangements affecting reactivity.
The molecular property that defines the location of electrons is the electronic charge density distribution. This property is essential as it determines the sizes and shapes of molecules, their electrical moments, and all of their chemical and physical properties. Qualitatively, the concept of electronegativity is related, as it reflects the ability of an atom in a molecule to attract electrons towards itself, hence influencing the distribution of the electronic charge.
Molecular structure and bonding are fundamentally influenced by electronic configuration. For instance, molecular orbital (MO) theory helps us understand that electrons within a molecule form bonding and antibonding orbitals due to constructive and destructive interference, respectively. This further determines the molecule's stability, reactivity, and magnetic character.
It's important to distinguish between electron-pair geometry, which includes all electron pairs, and the molecular structure, which only includes the placement of atoms, not the electrons. Hence, the molecule's properties such as melting and boiling points, solubility, density, and reactivity are affected by its geometry, predicted from its Lewis electron dot structure that highlights the arrangement of electron pairs.
