When chains are long many Vander Woals bonds are formed.So inter molecular forces become stronger.And the molecular mass also high in long chains.So they are densities also high.

What is the difference between a short-chain and a long-chain hydrocarbon?
short chain hydrocarbons have a low boiling and melting point whereas high chain hydrocarbons have a higher boiling and melting point. Also, short chain hydrocarbons have a low density and higher ones have a higher density. :)
How are small hydrocarbons different from larger hydrocarbons?
shorter hydrocarbon chains are easier to ignite, less viscous, a lower boiling point and more volatile. this makes them more useful, so longer chains are often cracked to make the smaller hydrocarbons
Which molecules have more than 1000 atoms?
Molecules with giant-covalent structures have thousands of atoms in them, and some examples include diamond, graphite, hydrocarbons with a relatively longer carbon chains, silica and carborundum.
Difference between natural gas and liquefied petroleum gas?
They are both Hydrocarbons Natural gas is mainly Methane, one atom of carbon surrounded by Hydrogen, CH3. Liquified Petroleum gas has longer chains of carbon, usually 3/4 Carbons (propane/butane, C3H8/C4H10)
How did chemistry change crude oil to useful materials?
Crude Oil is a mixture of various chemicals, the vast majority being 'hydrocarbons' made from Hydrogen and Carbon atoms only. When they are all mixed together, they have no particular use (crude oil without refining is pretty useless!). However,these hydrocarbon molecules form in chains a bit like necklaces, the longer the chain, the the higher the boiling point (longer chains tangle up). This means that they can be separated by using a process called 'fractional distillation'. Once separated, each hydrocarbon fraction has different properties. In general terms, the smaller the chain, the more useful it will be. Smaller molecules would have a lower boiling point (separate more easily), be more flammable (they need less Oxygen to burn) and be less viscous (all as a result of being made from smaller molecules which don't 'tangle' together). The longer chains like bitumen, can actually be 'cracked' into smaller chains in order to make more useful products like propane. This also forms molecules with 'double bonds'. These can actually be stuck back together to form unnaturally long molecules in a process called polymerisation. This forms molecules not found in nature which can have useful properties. Plastics and man made fibres can be made in this way.
How is crude made into products?
Crude oil contains mixture of various types of hydrocarbons. The hydrocarbons are separated by fractional distillation. Different hydrocarbons have different boiling points and therefore after crude oil is heated, shorter chains of hydrocarbons which have lower boiling point will become gas and can be easily separated one by one from hydrocarbons with shorter chains to longer chains. The brief products are Petroleum Gas, Gasoline, Kerosone, Heating Oil, Lubricating Oil and Bitumen in order of increasing molecular size.
Do elements with higher boiling point have longer or shorter molecule chains?
In general they are longer chained molecules.

How are hydrocarbons different?
One of these hydrocarbons is longer than the other.

Do small hydrocarbons have with only a few carbon atoms have low or high boiling points?
The lower the carbon chain, the lower the melting point. As the carbon chain gets longer (ie: larger hydrocarbons), the melting point gets higher.
Can Acetylene Gas be used to form long chain hydrocarbons?
I have heard that Methane can be used to form longer chain hydrocarbon fuels, -why not the much higher energy bonded Acetylene?
Why must gas shipped in the winter to the Northern states different from the gas shipped in the summer to the southern states?
Gasoline best burns when it is vaporized. Longer chain hydrocarbons, or less branched dhain hydrocarbons have a lower vapor pressure. These burn easier at higher temperatures than at cooler temperatures.
Is it easier to push the swings if its chains are longer?
Yes Or No?
What do long chains of amino acid create?
Short chains of amino-acids are called polypeptides, while longer a-a chains become, and form, proteins.
What are some trends in the Swing Sets industry?
A trend I see in the swing set industry is having longer chains on the swings. I believe the longer chains are in place so that even smaller kids can have access to the swings. By having longer chains, you allow a wider audience to use your swings.
