Planning

My aim for this experiment is to see the energy produced of different alcohols.

Variables involved:

For this experiment I would expect to have 3 different variables, Independent, Dependent, and fixed variables, which all helps me to plan and explain the experiment thoroughly.

The Independent variable (things you change), the thing that I will be changing in this experiment into the combustion of a range of alcohols, would be five different alcohols, Methanol, Ethanol, Propanol, Butanol, and Hexanol, which will help me to investigate combustion of different alcohols. I will measure these individual alcohols by mass which will be measured in grams, I'll be making two readings of each alcohol before the experiment and after, which would tell me the mass lost and how much heat in produces in 5 minutes.

Dependent Variable (things that you measure) the things that I'll be measuring would be the temperature (oC) increase by every minute of each different alcohol being lit to heat the water in the copper calumeter, and the mass before and after the experiment of alcohols.

Fixed Variables (Things that you keep the same) the things that I have chosen
