What is the hypothesis for soda and Mentos experiment?
Hypothesis: If a certain amount of Mentos are dropped into a container of soda, then the container with the most Mentos dropped into it will produce the most CO2 at the fastest rate. This will happen because the dissolved CO2 will provide the most nucleation sites to come out of the solution.
What is a good hypothesis for Mentos and Diet Coke?
Hypothesis: If the amount of soda in the bottle decreases, then the height of the plume and velocity of the liquid will also decrease because there will less liquid with which the Mentos can react.
What is the conclusion of Mentos and Coke experiment?
As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption.
What is the aim of the Coke and Mentos experiment?
The goal of this project is to explore the eruption of carbon dioxide when the candy Mentos dissolves in Diet Coke.
What are the variables in the Coke and Mentos experiment?
The variable could be something like the number of mentos dropped into the bottle, the flavor of diet soda, the size of the bottle, or the temperature of the soda.
What are the variables in the Mentos and Coke experiment?
Is Coke and Mentos a physical or chemical change?
physical change
Mixing Coke and Mentos looks like a chemical change, but since the gas released is carbon dioxide AND it was present before the foaming happened, it is actually a physical change.
What is the dependent variable in an experiment?
A dependent variable is what changes as a result of the independent variable manipulation in experiments. It’s what you’re interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)
