In any engineering application, time plays an essential role. Be it keeping an eye on the reaction time or calculating the efficiency, measuring time accurately is very important in synchronizing different processes.
In any industrial process, we require transportation of chemicals over long distances. It would be promising if we could use the same mechanisms to measure time and reduce equipment. Chem-E-Tempore tries to accomplish that by giving you a challenging model-making competition to measure time without any electrical components and control a reaction using it.
Q.1 When should the reaction start?
It should start automatically after a minute and within 3 minutes(maximum of 5 minutes). The time will be measured using a stopwatch.
Q.2 What chemical reactions can I use?
Any non-toxic and non-flammable exothermic reaction will suffice. Here are a few examples:
- The catalytic decomposition of hydrogen peroxide using FeCl3, MnO2, etc.
- The reaction of Aluminium foil with water in the presence of bases like NaOH, KOH, Ca(OH)2, etc.
- Acid-base neutralization like HCl and NaOH, HNO3 and KOH, etc.
Q.3 Where can I get the chemicals?
For testing a chemical reaction, one can borrow the chemicals from the chemistry lab after taking due permission from the authorities.
For purchasing chemicals, shops are located near Hanamkonda Bus Stand. Zeal Chemicals, Aditya Chemicals, etc are some of them. Participants from colleges other than NIT Warangal will have to get their own chemicals.
Q.4 How do I make the reaction start within the given time?
One can use various mechanical or chemical mechanisms.
Say, if you have a liquid reactant. It can be placed above a thick and viscous liquid like honey in a syringe. A certain volume of honey can be emptied within 1-3 minutes. The reactant will start flowing through the syringe once the honey empties completely.
You can also use a pulley mechanism. A weight can be attached to one side of the pulley and to the other side a cork which is restricting the flow of the reactant. As the weight moves down the cork will unleash the reactant into the vessel.
Q.5 How much is the prize money and when will we get it?
Once the event is over, the participants will be awarded the certificates and the money. The prize money will be disclosed at the day of the event.
Q.6 What if one or more criteria specified in the rules' section are not met with?
Teams won't be disqualified for not keeping up with the restrictions, though marks may be deducted. The abstracts don't have to be very detailed. A basic idea of your model will be sufficient.
