Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
What is the Boiling points of salt water?
It depends on the concentration of salt in the water.
Why does ammonia have higher melting and boiling point than methane?
Ammonia (NH₃) has higher melting and boiling points than methane (CH₄) due to the presence of hydrogen bonding in ammonia. The nitrogen atom in ammonia is highly electronegative, creating a dipole moment and allowing for strong intermolecular hydrogen bonds between ammonia molecules. In contrast, methane is nonpolar and primarily experiences weaker van der Waals (London dispersion) forces. As a result, the stronger intermolecular forces in ammonia lead to higher melting and boiling points compared to methane.
What separation technique is used to separate methane from a mixture of gases methane and ethane?
The separation technique commonly used to separate methane from a mixture of methane and ethane is cryogenic distillation. This method exploits the differences in boiling points of the gases; methane has a lower boiling point (-161.5 °C) compared to ethane (-88.6 °C). By cooling the mixture to very low temperatures, methane can be condensed and separated from ethane. This technique is effective for purifying natural gas and other hydrocarbon mixtures.
How do the melting and boiling points of water different from those of a sugar water solution?
it is pie
Methane and ethane separating method?
Methane and ethane can be separated through a process called fractional distillation, which takes advantage of their different boiling points. The mixture is heated in a column, and as the temperature increases, the components with lower boiling points vaporize first and are collected at different levels of the column. This allows for the separation of methane and ethane based on their boiling points.
Is liquid methane colder than liquid nitrogen?
No, at their boiling points liquid nitrogen is colder than liquid methane.
How do the melting and boiling points of water differ from those of a sugar water solution?
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
What is the Boiling points of salt water?
It depends on the concentration of salt in the water.

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.
At sea level water boils at 100 degrees Celsius while methane boils at negative 161 degrees Celsius Which has a stronger attraction between particles?
Water, because water exhibits 'hydrogen bonding' . So more energy /heat is required to break the hydrogen bonds for liquid water to become a vapour/gas. Methane does NOT have hydrogen bonds. In water molecules , the oxygen atoms bonds directly to two hydrogen atoms, leaving two sets of lone pairs of electrons. Oxygen is also a very electronegative element and so attracts electron denuded regions of other molecules towards itself. So the hydrogen atoms of an adjacent molecule will be denuded of electrons , so the lone pair of electrons on an oxygen atom will be attracted to this denuded region on an adjacent hydrogen in another molecule. This is called ' hydrogen bonding'.
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
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.
Is there a difference between boiling points of sea water and tap water?
Yes

What are Boiling points and freezing points examples of?
boiling points are when a substance starts to boil. example- water 32degrees F A boiling point is when a liquid evaporates to form a gas. freezing points are when a substance starts to freeze. example- water 212degrees F A liquid freezes to a solid below its freezing point.
