The heat flux, or the rate of heat transfer per unit area, is measured in watts (watts) only a. true b. false

The given statement is false.

Explanation:

Heat flux is defined as the flow of heat or energy per unit time in per unit area. S.I. unit of heat flux is watts per square meter.

Heat flux is represented by the symbol .

So, it means heat flux is not measured in watts only as it includes per unit area also.

Therefore, we can conclude that the given statement heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only, is false.

an acid is any substance that has pH of less than 7. The pH scale is used to measure how acid or alkali a substance is:

Explanation:

0-3 = strong acid (UI turns red)

4-6 = weak acid (UI turns orange/yellow)

7 = neutral (UI turns green)

8-10 = weak alkali (UI turns blue)

11-14 = strong alkali (UI turns purple)

The pH of an acid is determined by the concentration of Hydrogen ions (H+) the substance has when in solution. All acids contain hydrogen ions when in solution; the higher the concentration of H+ ions, the lower the pH.

Fast Fact: Bee stings are acidic. They can be neutralized using baking powder which contains sodium hydrogen carbonate.
