What holds cellulose molecules together in bundles large enough to form fibers?
Hydrogen bonds hold cellulose molecules together in bundles large enough to form fibers..
What is the hypothesis describing the behavior of molecules when a substance changes from a gas to a liquid?
The hypothesis regarding the behavior of molecules when a substance changes from a gas to a liquid is that as the temperature decreases, the kinetic energy of the molecules decreases, causing them to come closer together and form intermolecular forces. Eventually, these forces become strong enough to hold the molecules together in a liquid state instead of allowing them to move freely as in a gas.
Why bare covalent molecules typically liquids or gases?
Bare covalent molecules are typically liquids or gases because they have weak intermolecular forces between the molecules. These weak forces are not strong enough to hold the molecules closely together in a solid form, leading to a lower melting point and boiling point. As a result, bare covalent molecules tend to exist as liquids or gases at room temperature.
How does a solid differ from a liquid phase on the molecular level?
In a solid phase, the molecules are tightly packed together in a fixed position, with strong intermolecular forces holding them in place. In a liquid phase, the molecules are still close together but have more freedom to move around, as the intermolecular forces are weaker.
What happens to the molecules of a liquid when it is cool?
When a liquid is cooled, the molecules lose energy and move more slowly. As a result, they come closer together and may start to form bonds or attractive interactions. Eventually, the liquid may reach a point where the attractive forces between molecules are strong enough to form a solid.

What does the temp have to do with boiling points?
Water boils at 100 degrees centigrade. Water molecules in a liquid are always bumping against each other, but the attraction between them is strong enough to keep them held to each other. It is not strong enough to hold them tight like in a solid, but it does keep them together in a liquid. As the temperature rises, the molecules move faster and faster. When the liquid reaches the boiling point, the attraction between the molecules is no longer strong enough to hold them together. A number of them move so fast, they leave the liquid. That is called boiling.
Why do gases difuses but not solid?
The intermolecular forces holding gas molecules together are not very strong and thus the molecules are free to move around freely. This allows diffusion. The intermolecular forces holding molecules of a solid together are rather strong, and the molecules thus cannot move very freely. This prevents diffusion.
What force keeps molecules in a fluid together, including the weak electromagnetic and strong nuclear forces?
The force that keeps molecules in a fluid together is a combination of weak electromagnetic and strong nuclear forces.

Why does a certain amount of moles of water occupy much more space as a gas than as a liquid?
Intermolecular forces between the molecules of a gas are not strong enough to hold the gas molecules together therefore they break down taking more space.
Is an ionic bond strong enough to hold atoms together?
Yes, the ionic bond is strong to held the two atoms together such as NaCl .
Can a boat go around the world?
yes if its strong enough and it has enough gas
Liquids are not rigid why?
Liquids are not rigid because the intermolecular forces of attraction between its molecules are not strong enough to hold them as closely as solids, but they are strong enough to ensure that liquids occupy a definite volume.
When a gas changes into a liquid do the molecules spped up or slow down?
When a gas changes into a liquid, the molecules slow down. This occurs as the gas loses energy through cooling and reaches a point where intermolecular forces become strong enough to hold the molecules close together in a liquid state.
Why is PVC for making window frames?
it is strong enough to hole the pieces together.
Why is steel used as a material of a bicycle?
It's strong enough, light enough, and relatively easy to join together.
