At the molecular level, the main difference between a solid and a liquid is the arrangement and movement of molecules. In a solid, molecules are tightly packed together in a fixed position, vibrating in place. In a liquid, molecules are more loosely packed and can move around each other, allowing the liquid to flow.

Why does the coefficient of viscosity of liquids increase with an increase in temperature?
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.
How does it explain some properties of matter like surface tension and capillarity?
Surface tension is due to the cohesive forces between molecules at the surface of a liquid, which allows them to form a thin film. Capillarity occurs due to the adhesive and cohesive forces between a liquid and a solid surface, causing the liquid to rise or fall in narrow tubes. These properties are explained by the intermolecular forces, specifically hydrogen bonding, that exist between molecules and contribute to the behavior of matter at the molecular level.
What is the change in entropy when an icicle melts at 2 degrees Celsius?
The change in entropy when an icicle melts at 2 degrees Celsius is positive because the solid ice is transitioning to liquid water, which has more disorder and randomness at the molecular level. The increased molecular motion and randomness in the liquid state contribute to an overall increase in entropy during the melting process.
What is the difference between float and displacer?
a float is usualy lighter then the liquid of which it has to measure the level and as the name suggests floats on the surface of the liquid.whereas a displacer is usually heavier then the liquid in which it is submerged and thus cannot float.displacer works on the bouyancy principle.
What causes friction between 2 surfaces that are in contact with each other?
Friction between two surfaces in contact is caused by the interactions between their irregularities at the molecular level. As the surfaces rub against each other, these microscopic protrusions interlock, creating resistance to movement. The rougher the surfaces, the greater the friction generated.
Are hydrates and an-hydrates different on a molecular level?
no they are not
Is Evaporation Is When Particles Escape From A Liquid?
Yes, that's basically what happens at the atomic or molecular level.
Compared to a solid the molecular bonds of a liquid are what?
This question does not make sense. Liquids are not molecules . If there are molecules in a liquid for example a covalent molecular compound such as CCl4 the strength of the molecular C-Cl bonds are the same whether the molecule finds itself in a liquid, solid or gas. What is true is that in a liquid the intermolecular bonds are weaker than the bonds within molecules, the intramolecular bonds..
How is temperature related to the solubility of a solid solute Why?
At the molecular level, temperature is inversely proportional to solubility. As the temperature of a liquid increases, the solubility of gases in that liquid decreases.
What happens to the molecular level when substances get hot?
When substances get hot, the molecules gain energy and vibrate more rapidly. This increase in molecular motion causes the substance to expand, changing its physical state (e.g. from solid to liquid or from liquid to gas) if the heating continues. Heating can also break the bonds between molecules, leading to chemical reactions and changes in the substance's properties.
What is happening to liquid evaporation in terms of bond and energy levels?
Evaporation is a phase change from liquid to gas, therefore it involves increased energy and decreased bonding on the molecular level.
Why can some plastics be remoulded but others can't?
on a molecular level they are different. the polymers they are made up of have different shapes
Why do different liquids evaporate at different rates?
This has to do with their boiling point, and their boiling point is connected to the cohesion between the molecules of the liquid. Different liquids have different boiling points because of the molecular forces between the molecules. At room temperature there is a certain amount of energy in the liquid, depending on the boiling point some of the liquid might be at a level to 'evaporate off' ie by becoming so energetic that it becomes gaseous.
What are the common idea of biological science?
The central dogma of biological science is essentially the causal link between ideas which exist at different levels.This starts at the molecular level where we consider the chemical reactions and mechanisms of enzymes and proteinsThis continues to the DNA (genetic) level where we consider the codons which will translate into the proteinsThis continues to the organelle level, the organ level, the organism level and then the relationship between organisms and then different species.hope this helps - bwabwa
What is the difference between the homo and lumo energy levels in molecular orbital theory?
In molecular orbital theory, the HOMO (highest occupied molecular orbital) is the highest energy level that contains electrons, while the LUMO (lowest unoccupied molecular orbital) is the lowest energy level that does not contain electrons. The difference between the HOMO and LUMO energy levels determines the reactivity and stability of a molecule.
A liquid dissolved in a gas results in a solution that is what?
A liquid dissolved in a gas forms a homogeneous mixture known as a solution. In this case, the liquid molecules are dispersed evenly throughout the gas molecules, resulting in a uniform distribution at the molecular level.
When the volume of a liquid in a tank decreases the level is?
When the volume of a liquid in a tank decreases, the liquid level in the tank also lowers. This occurs because the amount of liquid present is reduced, resulting in a corresponding drop in the height of the liquid column. The relationship between volume and level is typically direct; as volume decreases, so does the level.
