Kenya has a pile of salt on the counter. she uses a pinch of it for a meal. which of the following physical properties of the salt changes?
a) density
b) shape
c) solubility
d) thermal conductivity

When Kenya uses a pinch of salt for a meal, the shape of the salt changes.

Salt is a common ingredient used in cooking. It adds taste to meals.

The properties of the salt listed are all intensive properties except for its shape.

Intensive properties are properties that do not depend on the amount of substance present but are characteristic of that particular substance.

The density, solubility and thermal conductivity of the salt are intensive properties hence they do not change but its shape does change.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
