Introduction

In this investigation, you will be observing ethanol that is on a glass dish, placed inside a chamber with a lid. You will monitor the CO₂ levels, temperature, and humidity (% water) in the chamber for 10 minutes once the ethanol is placed inside, burned with a lighter, and the chamber is closed. You will also monitor and record the mass of the ethanol in the petri dish. This information will be used to answer the questions:

Where did molecules move?

How did molecules molecules change?

What is happening to the energy?
