Conclusion

Various safety measures will be taken, i.e. wearing goggles. Making sure the apparatus is set up correctly and safely. Not carrying the alcohol burners around when lit. Predictions I predict that the different alcohols will heat the water, losing different amounts of weight, due to the different energy properties. The different bonds that need to be broken to release the energy, which occurs within in each alcohol. Measurements. ...read more.
