PH measures the concentration of Hydrogen ions in a substance.

a. True
b False

True

Explanation:

if you take p of anything it becomes pSomething. like p of cats is pCatsp of dogs is pDogs...therefore here pH is p of hydrogen ions (H is the atomic symbol for hydrogen) and therefore pH does measure concentration of free hydrogen ions in substance.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
