Which change of state do atoms or molecule become more ordered?
melting
When do atoms or molecules become more ordered?
Atoms or molecules become more ordered when they move from a higher energy state to a lower energy state, such as during a phase change from a gas to a liquid or a liquid to a solid. This process typically involves a decrease in entropy, leading to increased order and structure in the system.
Are atoms more ordered during melting or condensation?
condensation.. i think...
What happens to oils when they undergo hydrogenation?
When oils undergo hydrogenation, they become more solid and have a higher melting point. This process changes their chemical structure by adding hydrogen atoms, making them more saturated.
Why do some atoms have higher melting points?
Atoms with higher melting points tend to have stronger interatomic forces such as metallic, covalent, or ionic bonds. These bonds require more energy to break, resulting in a higher melting point. Additionally, the arrangement of atoms in the crystal lattice can also contribute to higher melting points.
Why do atoms become less packed?
Atoms become less packed due to factors like increased temperature, which causes them to vibrate more and move apart, leading to expansion. Additionally, phase changes, such as from solid to liquid, result in a less ordered arrangement of atoms. Changes in pressure can also influence atomic packing, as lower pressure allows atoms to spread out more. These factors contribute to the overall decrease in atomic density.
How is chocolate melting related to an amorphous solid?
Chocolate melting is related to an amorphous solid because chocolate has a disordered atomic arrangement, similar to that of an amorphous solid. Upon heating, the atoms in chocolate move more freely and lose their ordered structure, leading to the transformation from a solid to a liquid state.
What is the motion of particles when it finishes melting?
When a substance finishes melting, its particles transition from a more ordered, fixed arrangement in the solid state to a more disordered, free-moving arrangement in the liquid state. In the liquid state, the particles have more kinetic energy and can move more freely past each other.
What does a negative change in entropy indicate?
The system has become more ordered.
Unlike sodium and chlorine some atoms become more stable by sharing electrons forming what?
Unlike the sodium and chlorine, some atoms become more stable by sharing electrons and therefore form the ionic compounds.
In order to fill their outer most shells and become more stable atoms form what?
In order to fill their outer most shells and become more stable atoms form BONDS.
When does a solid turn in to a liquid?
When a solid turns into a liquid, it undergoes a melting process. Every material has a melting point, the temperature at which the solid turns into a liquid. When this point is reached, the atoms have become agitated enough that they spread out, causing the rigid structure of the solid to become more fluid. For example, water's melting point is above 32 degrees Fahrenheit. If the temperature goes below that, water freezes into a solid. Above 212 degrees, and it evaporates into a gas.
