Why alcohols boiling point is 100 degree celsius and water 1is lower 78 degree celsius?
Water boils at a higher temperature than alcohol(ethanol) as the inter-particular bonding is stronger. Water is held together by hydrogen bonding and although ethanol is also held together by hydrogen bonding, it is weaker due to the CH3CH2- group keeping the hydrogen bonds separated.
Water boils at ~100 oC whereas alcohol boils at ~78 oC.

Why do alcohols have lower boiling points than the corresponding carboxylic acids?
Alcohols have low power Vander woals bonds.Carboxilic acids have Hydrogen bonds as inter molecular bonds.
The difference of hexane and butanol in boiling point?
Hexane has a lower boiling point compared to butanol. The difference in boiling points arises from the difference in molecular weights, functional groups, and intermolecular forces present in the two compounds. Butanol, with its hydroxyl group, exhibits stronger hydrogen bonding interactions, leading to a higher boiling point compared to hexane.
How can petrol and kerosene be separated from each other when they are mix together and the difference between their boiling points is 25 degree celsius?
Petrol and kerosene can be separated by a process called fractional distillation. Since there is a 25-degree Celsius difference in their boiling points, they can be heated, and the component with the lower boiling point (in this case petrol) will vaporize first and can be collected separately, leaving kerosene behind.
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
Which metal has boiling point less than boiling point of water?
Gallium has a boiling point of 93°ish F. But mercury is way lower than that. It's a liquid at room temperature.
The temp of boiling water in Celsius?
The temperature of boiling water in Celsius is 100 degrees.
What degree celsius does water change from liquid to gas?
I'm pretty sure that it is a 100 degree Celsius because when water is boiling it becomes a gas so I think I'm right Added: But it is dependant of pressure. When you are high in the mountains water is boiling easier and at lower temperature because of the lower pressure (Henry's Law, I believe). Boiling eggs in boiling water at 95 oC will take significantly longer!
Temperature of boiling water at sea level?
The temperature of boiling water at sea level is 100 degrees Celsius or 212 degrees Fahrenheit. At higher elevations, the boiling point of water is lower due to decreased atmospheric pressure.
What is colder 17 degree Celsius or 30 degree Celsius?
17 degrees Celsius is colder than 30 degrees Celsius. The lower the temperature in degrees Celsius, the colder it is.

Why do aldehydes and ketones have lower boiling points than their correspending alcohols?
Ketones and aldehydes do not have hydrocarbon atoms which bond to nitrogen or oxygen, individual molecules do not hydrogen bond to each other which makes them have lower boiling points than alcohols.

Does a lower Celsius number mean colder?
Yes, a lower Celsius number indicates a colder temperature. The Celsius scale is based on the freezing and boiling points of water, where 0°C is the freezing point and 100°C is the boiling point. as the number decreases, the temperature decreases.
Why upper fixed point and lower fixed point are not 100 degree celsius and 0 degree celsius respectively of pure water in kathmandu?
The boiling point and freezing point of water are affected by factors such as altitude, atmospheric pressure, and impurities in the water. In Kathmandu, being at a higher altitude, the boiling point of water is lower than 100 degrees Celsius and the freezing point is higher than 0 degrees Celsius due to reduced atmospheric pressure. Therefore, the upper fixed point and lower fixed point of pure water in Kathmandu will not be at 100 degrees and 0 degrees Celsius respectively.
