Altering the Boiling Point of Water
Aim:
To investigate if any of the substances: Honey, Sugar, Salt, Baking Soda or Ethanol can alter the boiling point of water.
Introduction
For three years running, Master Chef has been my favourite television show. And whenever I watch it, I always see how every single second could make a difference and one day, I witnessed my favourite contestant get eliminated on the back of cooking meat in the pressure cooker where it needed literally one more minute. I was very devastated and decided to do this experiment on this very basis. I was out to find some any day ingredients which could lower the boiling point of water.
A bit of research on Wikipedia.com and swri.org and found out that a something called the volatile and non-volatile solutes which I will explain later. There was something in these substances which when mixed with water or any other substance would either drop or raise the boiling point. I have decided that over a two day course, I will be testing six different substances three different times to get a more accurate reading. I will then average out the results to get one accurate answer and make a table and a graph of it. In my discussion I shall discuss why and how and what the benefits are of this and conclude my findings. My research will help by trying to find substances that cut down the wait time on something to boil such as a hardboiled egg or a pressure cooker or in anti-freeze. Antifreeze helps the radiator from freezing and also elevates the boiling point of the fluids well. By raising the boiling point, it helps to protect against boil-overs.
Hypothesis:
If we add Ethanol or Baking Soda to the water, these variables will cause the boiling point to decrease whereas the remaining four variables will cause the boiling point of the water to elevate.
