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
Answer:
butane will be in gaseous state at 25 degrees and will be solid at -150 degrees.
Explanation:
As 25degrees is the room temperature so the state of butane at 25 degrees will be gaseous while the butane will freeze at -150degrees as it's beyond its melting point, it means it melts at -140degrees , it clearly shows that it exists in solid state before -140degrees.,
