what are extremely viscous?

Answer 5

long chain hydrocarbons

Question 6

what does flammability tell us?

Answer 6

how easily a hydrocarbon combusts

Question 7

what hydrocarbons are extremely flammable?

Answer 7

short chain

Question 8

what happens to flammability as size of hydrocarbon molecules increase?

Answer 8

they get less flammable

Question 9

what is the boiling point?

Answer 9

the temperature at which a liquid turns to a gas

Question 10

what are all hydrocarbons at room temperature?

Answer 10

gas due to boiling points being very low
