Question: In the UK, what type of installation requires a fireman's switch?

1. Neon Lighting
   
2. High Pressure Sodium Lighting
   
3. Water Features
   
4. Hotel Rooms
   

Incorrect Answer

Correct Answer
Neon lighting runs at a high voltage, typically above 1000 Volts. A fireman's switch protects a fireman from receiving a shock when a water jet is sprayed onto the installation. The switches are red, and mounted in a conspicuous position. (This is specified by IEE Regulations (Europe), SANS (South Africa), UK Electricity regulations and many Asian countries. I am unable to confirm other countries' requirements, so feel free to let me know.)

Question: Breaking of a larger hydrocarbon molecule into a smaller one by heating in the presence of a catalyst is called ___.

1. Cracking
   
2. Orthofugation
   
3. Centrifugation
   
4. Thermogenation
   

Incorrect Answer

Correct Answer
Cracking is done so as to meet the increasing demand of petrol. For example Dodecane(C12H26) is cracked into Heptane(C7H16) and Pentene(C5H10) by heating intensely with the presence of a catalyst. The new hydrocarbons are similar to the hydrocarbons of gasoline. Nowadays however, synthetic petrol is also used widely. This is produced by mixing powdered coal with heavy oil and passing hot hydrogen gas over it.
