What is the biggest chain reaction?
College student Evan Voeltner perfects his design for Reactica at The Tech Interactive in San Jose, CA. The team, led by Alex Huang, will attempt to set the Guinness World Record for longest chain reaction by building more than 412 mechanical steps.
What are some examples of chain reactions?
Examples from chemistry are burning a fuel gas, the development of rancidity in fats, “knock” in internal-combustion engines, and the polymerization of ethylene to polyethylene. The best-known examples in physics are nuclear fissions brought about by neutrons.
What is chain reaction called?
A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events. Numerous chain reactions can be represented by a mathematical model based on Markov chains.
What are some ideas for a Rube Goldberg machine?
You can use almost anything to create your Rube Goldberg machine. Here are some ideas: dominoes, fans, PVC pipe, magnets, duct tape, marbles, cups or bowls, miniature toy cars, paper towel tubes, string. As you create your machine, follow your blueprint and place your materials where you think they need to be.
What is the longest Popsicle stick?
The structure stands tall at a height of 6.157 m (20.20 ft). Eric Klabel decided that he wanted to pursue a record of his own after witnessing other record-holders in a video by Guinness World Records, as per the Guinness website.
Is fire a chain reaction?
A fire is an example of a chemical chain reaction. A chemical chain reaction is a series of chemical reactions where the products of the reaction contribute to the reactants of another reaction. This transformation of products to reactants allows a reaction to continue with minimal or no outside influence.
Who invented chain reaction?
Enrico Fermi, the Italian-born Nobel Prize-winning physicist, directs and controls the first nuclear chain reaction in his laboratory beneath the bleachers of Stagg Field at the University of Chicago, ushering in the nuclear age.
Why is uranium good in making electricity?
It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
What is U 239 in what ways is it different from U 238?
In what ways is it different from U-238? U-239 is an isotope of uranium. It has one more neutron in the nucleus than U-238.
What are the six simple machines Rube Goldberg?
A Rube Goldberg Machine is “a comically involved, complicated invention, laboriously contrived to preform a simple operation.” 2. What are the 6 Simple Machines? A. The 6 Simple Machines are: wedge, screw, lever, wheel and axel, inclined plane and pulley.
