What the correct answer?
alexandr402 [8]

B. Bleach and sea water should be identified as bases

Explanation:

  • The pH scale measures the acidic or basic nature of a substance.
  • Ranges from 0 to 14.
  • If pH is lower than 7 → the solution is an acid.
  • If pH is more than 7 → the solution is an basic or alkaline.
  • If a pH is a 7 it is neutral.

In the given question, the pH scale measures for bleach is 8 and for sea water it is 13. So, bleach is basic, not neutral and Sea water is basic too instead of acid. So, Bleach and sea water should be identified as bases.

Upon heating a copper sample will expand, leading to a lower density? <br><br>A) True<br>B) False
Leona [35]

Answer;

The above statement is true

upon heating a copper sample will expand, leading to a lower density

Explanation;

-The density of solids decreased with increase in temperature and vice versa. The increase in temperature causes the volume of the solid to increase which as a result decreases the density as Density=Mass/Volume. The temperature of a body is the average kinetic energy of the molecules present in it.

In other words; The temperature of a body is the average kinetic energy of the molecules present in it. Therefore; when heat is supplied ( or temperature is increased) the average kinetic energy increases which increases the volume and thus density decreases.
