How Do Different Substances Affect The Burning Of Rocket Fuel

460 Words2 Pages

THE RESULT OF ADDING DIFFERENT SUBSTANCES TO ROCKET FUEL.

Name: Gareth Murdoch/Devan Garland
Teacher: Mr Adams
Class: Grade 9A

Introduction
The reason we chose this project was to find out what an inexpensive way to make rocket fuel for Mini projects and to experiment to find what substance you can add to make the fuel more effective in speed and burning rate.
Investigative Question
How do different substances affect the burning of rocket fuel?

Hypothesis
Water makes the rocket fuel burn quicker.

Variables
Independent Variable - The amount of potassium nitrate used.
Dependent Variable – Amount of white sugar used.
Controlled Variable – Heat of stove.
Method
1. Pour 40g of sugar into a pot.
2. Pour 60g of potassium nitrate into the same pot.
3. Cook the mixture until caramelised.
4. Get the container of …show more content…

Discussion and Conclusion and Relevance
Discussion

What do my results mean?
It means that the more potassium nitrate you add to the mixture the faster the rocket fuel will burn.

How could I improve my experiment?
I could improve my experiment by:
• Measuring the temperature of the stove before placing the pot on it
• By weighing the quantity of Potassium Nitrate instead of measuring it out
What were the sources of error?
• Temperature of the stove
• Amount of sugar
What would be the next step further
The next step further would be to make a rocket and test the effectiveness of the fuel

A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.

Unknown White Compound Lab Report

Some compounds have very distinctive colors when burned, such as Potassium, which is a white/purple, and sodium, which is a deep red hue. The first step for a flame test is to gather the needed materials. These include beakers, distilled water, the unknown substance, a Bunsen burner, matches, a nichrome wire, tubing to connect the gas line to the Bunsen burner, goggles, and known compounds to compare with. The first step is to make aqueous solutions of all the substances to be tested. This is done by adding .5

How Fast Does Alka Seltzer Make Gas

621 Words | 3 Pages

The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.

Repeat steps 1-10 for two more trials. Conclusion: 1. I chose to compare temperature and amount of reactants in my experiments. I chose these because I thought they would reveal the the most drastic time differences. I also chose these factors because I had prior knowledge of them before I even started chemistry.

Alka Seltzer Experiment

794 Words | 4 Pages

In this particular experiment the constant condition, the factor that was never changed, was the room temperature water. The independent variable, the variable the student affected, was how much water was placed into the beakers. The dependent variable, a variable that was affected by the independent variable, was the time it took for the tablet to fully dissolve. The control group, which did not receive treatment from the students, was the 50 ml of water as a result of being the medium between the three measurements of water. Finally, the experimental group, the subject that was exposed to the variable during the experiment, was the 25 ml and 75 ml of

The Rocket Boys Sparknotes

After one such experiment with a particularly good reaction, Quentin says, "I think we've got our next rocket propellant,"(224). The Rocket Boys had reached the maximum results they were going to get from their old propellant, so they needed a new one. This experiment features lots of gas and smoke, which are two things that help drive a rocket, so it can be inferred that this new rocket propellant will make a good propellant. A better propellant will help them reach higher altitudes, which were

Developing a topic for Science Fair will never be easy unless you have a little background about that certain topic. One particular scientist is developing her topic by researching questions she has that revolved around her topic. The scientist will be researching how water temperature can affect the chemical reaction rate between baking soda and citric acid within a bath bomb. The independent variable will be the temperature of the water (mL). The dependent variable will be the chemical reaction rate which is formed by baking soda (g) and citric acid (g).

Pipet Rocket Lab Report

1276 Words | 6 Pages

In Table 1, Trial 1 and Trial 2 contain two mol of oxygen reacting with four mol of hydrogen to obtain that 1:2 ratio. As seen in the observation of distance the rockets flew, the farthest distances were found to be when this ratio was used. Also, the rocket that flew the farthest in the entirety of Table 1 was found in Trial 2 when oxygen was added to the pipet first. This observation does coincide with the hypothesis which predicted the addition of oxygen to the system first would produce the greatest propulsion. The remaining trials typically followed a trend characterized by a decrease in distance flown with an increase in the number of moles of oxygen in the combustion reaction.

Coke And Mentos Experiment

Many people conduct experiments resulting in explosive reactions without even understanding the science behind them. This can mean added danger for everyone in the lab, not to mention that it takes all the fun out of the experiment. One experiment in particular, involving Diet Coke and Mentos, can be easily manipulated in which several factors increase or prohibit the reaction. Contrary to popular belief, the reaction that occurs within this mixture is physical rather than chemical. All the components necessary to form the reaction are present at the beginning, as well as the end.

VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.
