What physical property does not identify a substance? boiling point ph brittleness

brittleness

Explanation:

Physical property is defined as the property of a substance which becomes evident during physical changes. Example: Melting point

1. Boiling point is the temperature at which vapour pressure of the liquid is equal to the atmospheric pressure.

2. pH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

3. Brittleness is the tendency of a material to break upon the application of a relatively small amount of force, impact, or shock.

Thus brittleness does not identify a substance.
