Dimas [21]3 years ago
3 0

Answer:

d.  Atoms are rearranged.

Explanation:

In a chemical reaction, what happens is that atoms are simply rearranged when the process takes place.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed but atoms are simply rearranged".

Therefore:

  1. Atoms are not created
  2. Atoms are not destroyed
  3. Atoms are simply rearranged.

Certain materials can become superconductors under what conditions?
tresset_1 [31]

Option (b) is correct. The certain materials can act as superconductors at a very low temperature.

Explanation:

The Superconductivity of a material is the property of the particular substance to provide no resistance to the path of the current through it. The current does not face any hindrance due to the motion of the other particles inside the conductor.

The superconductivity of a substance leads to the flow of current through the substance or the material without any hindrance. The resistance of a substance is due to the motion of the particles inside it. If all the motion occurring inside the substance are seized, there will be no resistance offered by the conductor.

Therefore, the superconductivity can be defined as the state where all the motions inside the a material are seized. This occurs at a very low temperature. The absolute zero temperature(0\text{ K or }-273^\circ\text{ C}) is regarded as the temperature where there is no motion in any particle.

Thus, Option (b) is correct. The certain materials can act as superconductors at a very low temperature.
