Answer:
water is denser
Explanation:
if you were to fill 2 55 gallon barrels of each product the water would weigh more because water is more dense
A.
to defend against infection
B.
to provide structural support
C.
to carry genetic information
D.
to process information
When the temperature of a substance decreases, the average kinetic energy of its particles also decreases. This is because the temperature of a substance is proportional to the average kinetic energy of its particles. The slower the particles move, the lower the kinetic energy.
The question refers to the relationship between the temperature of a substance and the average kinetic energy of its particles. According to the kinetic-molecular theory, the temperature of a substance is proportional to the average kinetic energy of its particles. When the temperature of a substance rises, the particles vibrate more in solids or move more rapidly in liquids and gases, indicating an increase in kinetic energy. Conversely, if the temperature decreases, the kinetic energy also decreases, and the particles move more slowly.
For instance, when the temperature of a gas increases, its average kinetic energy increases, more molecules have higher speeds and fewer molecules have lower speeds. The distribution shifts towards higher speeds overall. If the temperature decreases, the opposite happens: the average kinetic energy decreases, more molecules have lower speeds and fewer molecules have higher speeds. The distribution shifts towards lower speeds overall.

(2) increases
(3) remains the same
Answer: option (1) decreases.
Explanation:
May be you have experienced that: when you go to the beach, where the atmposhpere pressure is greater than the atmosphere pressure in places that are at higher altitudes, the water takes longer to boil. That is because the boiling temperature is greater, and you need more total heat (more time) to permit the liquid to reach that temperature.
The reason why that happens is because substances boil when the vapor pressure (the pressure of the particles of vapor over the liquid) equals the atmosphere pressure. So, when the atmposhere pressure increases, the temperature at which the vapor pressure reaches the atmosphere pressure also increases, and when the atmosphere pressure decreases, the temperature at which the vapor pressure reaches the atmosphere pressure decreases.
B. Electron pairs repelling each other push atoms apart
C. Valence electrons modify core electron orbitals
D. Intermolecular forces distort electron bonds
Answer:
B. Electron pairs repelling each other push atoms apart
Explanation:
The VESPR theory explains molecular shape by suggesting that electron pairs repelling each other push atoms apart.
If an atom is bonded to two or more other kinds of atoms as in many covalent molecules and ions, the shape of the system is determined by the geometry of the bonds around the central atom.
