If the graph has no trend which means almost constant, it indicates that the dependent variables will not change when the independent variables change.
You did not add the answers, but a non-living factor that could contribute could be temperature.
The thin flat layering found in most metamorphic rocks is called the FOLIATION....(sorry,thats all i know)
Answer:
(2) Boiling point order: Methanol (highest) > Methanal > Methane (weakest)
(3) Boiling point of alcohol will be higher than ester molecules
Explanation:
(2) Methane is a non-polar molecule. Hence only weakest van der waal inter molecular force is present between methane molecules.
Methanal is polar molecule due to presence of polar aldehyde group. hence weaker dipole-dipole inter molecular force is present between methanal molecules.
Methanol is a polar protic molecule. Hence strongest H-bonding force act between methanol molecules.
The stronger the inter molecular force, the higher will be boiling point.
Boiling point order: Methanol (highest) > Methanal > Methane (weakest)
(3) An alcohol is a polar protic molecule. Hence strongest H-bonding force exist between alcohol molecules.
An ester is polar molecule. Therefore weaker dipole-dipole inter molecular force is present between ester molecules.
So boiling point of alcohol will be higher than ester molecules.
