What hydrocarbons has the lowest normal boiling point?
Pentene
Why are different hydrocarbons have different melting points?
hydrocarbons have different boiling point, the greater the size, the higher the boiling point. This is easily explained by if you imagine a bowl of spaghetti- it is easier to pull out a small strang (it takes less energy). It is the same with hydrocarbons hope that helps
Which petroleum product has the lowest boiling point?
The fraction of crude oil that has the lowest boiling point is the Liquified Petroleum Gas, which is a mixture of small hydrocarbons(methane, ethane, etc).
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.
Is the fractionating tower hotter at the top or the bottom?
The bottom - this is why the hydrocarbons with the shortest chains leave the tower at the top as they have a lower boiling point.

How can you separate hydrocarbons from crude oil?
By using the boiling point of each substance to separate it out

How does boiling point and melting point find a substance?
what is the melting point and boiling point of substance
Why is distillation is a good way to separate hydrocarbons?
Because they evaporate at different rates, each has a different boiling point.
Do long hydrocarbons have a higher boiling point then short hydrocarbons?
This is true as far as we are talking about alkanes. As the size of an alkane chain increases the boiling point increases because the relatively low van der Waals forces increase with mass. The higher the vdw forces the more energy required to break apart two molecules and thus higher 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.
Is it true that in fractional distillation of petroleum low-boiling hydrocarbons come out first?
Yes Since they have a lower boiling point, they have a higher vapor pressure - or to be more exact, a higher fugacity, than the higher boiling point components at the same temperature.
Is the fractionating tower hotter at the top or the bottom?
The bottom - this is why the hydrocarbons with the shortest chains leave the tower at the top as they have a lower boiling point.
How do you find highest boiling point of an element?
After repeated measurements of the boiling point for all elements; rhenium has a boiling point of 5 596 0C.
How you can find boiling point of liquid?
at which temprature first bubble form of liquid its called boiling point.
