Dear Boiling Water-ologists,

As a sheepy I of course luff to boil water. Boiling water is my all time favourite heating-water-up past time. There’s so many uses for boiling water…ewe can cook peas or melt a snowman……well there ewe are !!..what more could ewe ask for ?

See my boiling water here ?




My Boiling Water Here.

Nice eh ?..


Now I know that if I add some salt it makes the water boil at a higher temperature yes ?…well..apart from taking it up a mountain is there anything I can add to my water to make it boil at a lower temperature ?



Whajafink ?

Hugs & shmishes


Mwah mwah

You could always dump some alcohol into it. Mind you, the alcohol will soon evaporate and you'll be back to water again.

If the kind of alcohol or, more generally, the chemical, added to water is non water-soluble, its vapour pressure would add to that of water, decreasing the water boiling point. This effect is exploited in chemistry, in steam distillation (in this case it's the opposite: the organic, non water-soluble chemical decreases its boiling point by adding steam to it):

Adding a chemical like ether, dispersing it in water, you shoud get good results.

Thank ewe both very much Geezer and Lightarrow.....so...once the alcohol/chemical has evaporated would the water stop boiling and only restart again once it then continues up to 100C ?


Cheers peeps.

Using a non water soluble chemical of the kind I wrote, both water and that chemical boil at a lower temperature. If the chemical's percentage is lower than water's perc., then it will vaporize completely before water, in the other case it'll be the opposite.

You could add altitude - that would change it's boiling point.  

At the peak of everest (8848m above sea level) water should boil at about 68°C.

Do you have any spare altitude, Neil?
