Project Question: I really need some topic ideas for Chemistry STEM project. Please advise if any below ideas are good: What is the boiling points of different liquids?, What kind light bulbs emit the most heat?, What kind of batteries last the longest?, What soap dissolves the fastest in room temperature water?, Which fruit has the most sugar? And, Melting rate of different kinds of candles? Please help me, Thanks, James

Best liquids to compare boiling points

Post by Ctran »

My 10th grade Science project will investigate why different liquids have different boiling points. What are common liquids should I select so I can buy/obtain? I am considering pure water, Vinager, witch Hazel, olive oil, alcohol. And how many liquids must be selected: 2 or 3? Thanks much, James

You will need water as a control. I recommend you to get alcohol for your project. You should get alcohol derived from alkane, such as ethanol, butanol, since they are different by 1 carbon atom. 3 to 5 alcohols are good numbers for this project. Ethanol, propanol and butanol are easiest to obtain. You can get them from hardware stores or drug stores.

Thank You! Can you expand on what you mean by using water as the control?
