Water boils at a higher temperature than methane because water is a polar compound. Each molecule is held together chemically. Each molecule is held to other molecules by hydrogen bonding. With Methane, it is every molecule for itself.

∙ 12y agoThe foces of attraction that hold water together are Hydrogen Bonds (the strongest intermolecular force); whereas Methane only has Van der Waals forces acting on it (the weakest intermolecular force).
When boiling a molecule the molecukar bonds don't break only the forces of attraction between those molecules break.

Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
What is the Boiling points of salt water?
It depends on the concentration of salt in the water.
How do the melting and boiling points of water different from those of a sugar water solution?
it is pie
What are 2 physical properties of ethyl alcohol and water to separate them?
Separation is possible by distillation because boiling points are different.
Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
Why boiling point of water is not fixed?
The boiling point of water is fixed but boiling points depends on the atmospheric pressure.
Why is the boiling point of methane much lower than the boiling point of hydrochloric acid?
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
What is the top of an oil fractionating column is?
The bottom is where the compounds with the highest boiling points are found. The ones with the lowest boiling points will be found at the top of the column.
What is the boiling point of any substance?
different substances have different boiling points, a main reference to boiling points is the boiling point of water (H2O) which is 100 degrees Celsius
Why methane and silicon dioxide have different boiling points?
They're very different compounds in nearly every way; it would be considerably more surprising if they had similarboiling points.
What is the Boiling points of salt water?
It depends on the concentration of salt in the water.
What are the freezing and boiling points in Fahrenheit and Celsius?
For water, the freezing points are Zero C and 32 F. The boiling points are 100 C and 212 F.
Can methane be a gas at -161.5c as it's boiling point?
Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.
The boiling temperature of water is so much higher than that of methane because water molecules are what?
Water is polar and is strongly hydrogen bonded.
Is there a difference between boiling points of sea water and tap water?
Yes
Does ammonia have a higher boiling point than methane?
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
