Why is it important to check the conductivity and pH of pure water for comparison
frozen [14]

it is important to check the conductivity and pH of pure water to:


1- to check the purity of water and if it healthy or not , and the water source.


2- we have to measure the PH to know the alkalinity or acidity of water. If the PH > 7 so it is acidic , if PH < 7 so it is alkaline.


3- we have to measure the conductivity of the water as it is an indication for the impurity level. and it shouldn't be high to keep the water healthy.

Which equation was used by Albert Einstein to explain the photoelectric effect? [E = energy, h = Planck’s constant, and v = freq
devlian [24]

Answer:

E = hV

Explanation:

Hello,

Photo electric effect theory was borne out the the confusing if light was either a particle or a wave. However Albert Einstein came up with a theory that light was a particle and each particle carry a certain amount of energy referred to as photons.

He used Max Planck's idea and theorized that since light is made up of photon, when each photon comes in contact with the surface of a metal, the energy is transferred to the electron.

E = hv

E = energy of the photons

h = Planck's constant = 6.626×10⁻³⁴Js

v = frequency of the photon in Hz
