How are water molecules packed when they are in a liquid?
They are linked to other water molecules by hydrogen bonds, which are relatively weak though strong enough to confer surface tension. They aren't static, there is fluidity because water molecules constantly bonding and unbonding with other watrer molecules.
What holds matched nucleotides together?
The hydrogen bonding across to the nitrogen's lone pairs in each match is strong enough in a correctly matched pair to hold the DNA molecules together.
Why are the forces that hold atoms together in molecules stronger than the forces that hold the molecules together in a gas?
Molecules are two or more atoms held together by a covalent bond. This is a very strong bond as it is held together by strong electrostatic charges. All covalent molecules (apart from those held together in a covalent lattice such as Diamond) are bonded to other molecules by Van der Waal forces. Its is these intermolecular bonds that control boiling and melting points. Van der Waals are (in this case) the attractive force between molecules, they are temporary bonds between temporary dipoles and as electrons orbit the nuclei of atoms the position changes. This temporary dipole induces other molecules to form induced dipoles. Strength varies due to shape of molecule (the more "oblong" the greater the strength of the bond) and by size (the greater the size the greater the strength of the bond.)
When the attractive forces holding particles together are strong enough to hold them together as a group but not as a fixed position they form a what?
Liquid. The liquid state lies between the gaseous and the solid state. The cohesive (attractive) forces between the liquid particles are strong enough to keep them together but not to keep them in a fixed position.
Why do elements stick together when they form chemical bonds?
A chemical bond requires energy to break it, therefore if the bond is strong enough then the atoms "stick" together
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.
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 .
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.
Do in freezing point the molecules of a substance in motion?
the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
Can a boat go around the world?
yes if its strong enough and it has enough gas
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.
Why can only gases can be compressed?
The molecules in a gas are always spaced out in a random pattern and without strong forces of attraction that hold them together in an orderly arrangement unlike liquids where the molecules are closely packed but not in a orderly arrangement and they cannot move freely, however can still move around, due to the not very strong forces of attraction between them, and solids, where the molecules are closely packed into an orderly arrangement and they can only move around in their fixed positions, therefore gas molecules can move freely and can be compressed into the spaces between them.
What force keeps the moons of Jupiter in orbit around the planet?
The moons stay in orbit around Jupiter by the force of gravity.
How do solid molecules move?
Not counting how they all move together as the object moves; each molecule moves around its own location (often said to vibrate) at a speed that depends on the temperature of the object. If the temp gets high enough, then the molecule(s) can break loose of the bonds that hold them in place ... either liquefying or evaporating. At absolute zero they don't move, theoretically (for that temp has never been reached).
