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.
No, at their boiling points liquid nitrogen is colder than liquid methane.
It depends on the concentration of salt in the water.

Separation is possible by distillation because boiling points are different.
No, the amount of water does not change the boiling or freezing point of water. The boiling point of water is always 100°C (212°F) at sea level, and the freezing point is always 0°C (32°F). The boiling and freezing points are determined by the chemical properties of water, not the amount of water present.
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.
No, at their boiling points liquid nitrogen is colder than liquid methane.
It depends on the concentration of salt in the water.
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.
Yes
Water is polar and is strongly hydrogen bonded.
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
Water has a stronger attraction between its particles compared to methane. This is evident in the higher boiling point of water, as the stronger intermolecular forces require more energy to break the bonds between water molecules. Methane, being a lighter molecule, has weaker intermolecular forces which results in a lower boiling point.
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.
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.

Water boils at 212°F. Iron's boiling point is 5,182°F. Quite a difference.
