Properties Of Hydrocarbons

Question 1

Definition viscosity

Answer 1

Tells us thickness of a fluid

Question 2

What happens to viscosity as the size of the hydrocarbons decreases

Answer 2

Less viscous

Question 3

What happens to viscosity as the size of the hydrocarbon increases

Answer 3

The hydrocarbon molecules get more viscous

Question 4

Definition flammability

Answer 4

How easily a hydrocarbon combusts (burns)

Question 5

Size of hydrocarbon and flammability relationship

Answer 5

Short Chain - extremely flammable
Long chains ( bigger in size) - very difficult to burn

Question 6

Definition boiling point

Answer 6

Temperature at which the liquid turns to gas

Question 7

Relationship between boiling and size of hydrocarbons

Answer 7

As the size of the hydrocarbon molecule increases the boiling point also increases
Short chain - low boiling point
Long chain - high boiling point

Question 8

What state are the first 5 hydrocarbons in at room temp and why

Answer 8

They are all gases

They have boiling points lower them room temperature
