Q.4) Consider the following statements:
1. Flammable ice consists of ethane trapped within water crystals
2. Flammable ice is highly flammable and energy-intensive fuel.
Choose the correct statements from the options given below
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Ans. B
Explanation:
- Flammable ice is also known as methane hydrate or methane clathrates.
- It consists of methane trapped within water crystals.
- It is the world’s largest natural gas resource which is trapped beneath permafrost and ocean sediment where low temperature and moderate pressure combine to trap methane in this specific way.
- The methane hydrate is highly flammable and energy-intensive fuel as one cubic metre of the compound can releases about 160 cubic metres of gas.
- It can break down into water and methane after temperature is raised or pressure is lowered.
- It is likely to be the world’s last great source of carbon-based fuel and has potential to be a revolutionary energy source that could cater future energy needs.
- Its vast deposits exist underneath all oceans around the globe, especially on the edge of continental shelves.
Q.5) Consider the following statements:
1. Muntra is an unmanned remotely operated tank.
2. Muntra can be used for surveillance, mine detection and reconnaissance in areas with nuclear and biological threats
Choose the correct statements from the options given below
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
Ans. C
Explanation:
- It is an unmanned remotely operated tank.
- Developed by DRDO.
- It has been launched in three variants:
- Muntra-S : For surveillance
- Muntra-M : For mine detection
- Muntra-N : For reconnaissance in areas with nuclear and biological threats. It is also likely to be used in Naxal-hit areas.
- The Muntra variants have surveillance radar, an integrated camera along with laser range finder which can be used to spy on ground target 15km away – heavy vehicles or crawling men.
