Answer:

D. The kinetic energy is greater after a substance changes from a

solid to a liquid

Explanation:

During a phase change from solid to liquid, the particles making up the mobile becomes more mobile and as a result there is an increase in kinetic energy of the system.

  • Kinetic energy is the energy accrued due to the motion of a body.
  • In a melting process where solids turn to liquid, there is an increase in kinetic energy.
  • When randomness of a system increase, kinetic energy also increases.
  • From liquid to gas and gas to plasma increases kinetic energy.
  • In the other way round, the kinetic energy reduces.

Dimethyl sulfide is the most abundant biological sulfur compound emitted to the atmosphere. It is produced by phytoplankton and
iogann1982 [59]

The structure of Dimethyl sulfide is H3C-S-CH3. It is produced naturally by some marine algae.

<u>Explanation:</u>

  • DMS or dimethyl sulfide is formed by using two methyl groups combined with one sulfur atom. It is an organosulphur compound with a structural formula H3C-S-CH3.
  • Most abundant biological sulfur compounds emitted to air and oceans by phytoplankton.
  • DMS is produced naturally by the waste of dimethyl sulphoxide which is disposed into the sewer causing environmental odor problems.
  • It is a flammable liquid that boils at 37 degrees celsius and a disagreeable smell produced from the cooking of certain vegetables also indicates bacterial contamination in the production of malt and brewing.
