Answer:

Work done=50J

Heat removed=29J

Now

\\ \sf\longmapsto \Delta E=-50+29

\\ \sf\longmapsto \Delta E=-21J

Hence the internal energy would decrease by 21J

  • Option B is correct

Give explanations for the large drops in melting point from C to Si and from Ge to Sn.
____ [38]

As we move down the group, the metallic bond becomes more stable and the formation of forming covalent bond decreases down the group due to the large size of elements.

Covalent and metallic bonding leads to higher melting points. Due to a decrease in attractive forces from carbon to lead there is a drop in melting point.

Carbon forms large covalent molecules than silicon and hence has a higher melting point than silicon.

Similarly, Ge also forms a large number of covalent bonds and has a smaller size as compared to that of Sn. Hence melting point decreases from Ge to Sn.

The order will be C>Si>Ge>Pb>Sn.

low level waste

Explanation:

Low level wastes are nuclear wastes generated from hospitals and industries as well as the nuclear fuel cycle, and is comprised of paper, rags, tools, clothing, filters, etc., which contain small amounts of mostly short-lived radioactivity.

  • Low level wastes are typically radioactive in nature and are difficult to dispose.
  • They originate from radioactive processes in the hospital and nuclear reactors.
  • There has been growing concerns about the safe disposal of radioactive wastes over the years.
  • They are made up of materials with short lived radioactivity.
