Question

Explain Rutherford's alpha particles scattering experiment?

Answer 1

Rutherford's alpha particle scattering experiment changed the way we think of atoms. Rutherford directed beams of alpha particles (which are the nuclei of helium atoms and hence positively charged) at thin gold foil to test this model and noted how the alpha particles scattered from the foil.

Answer 2

It is because at same temperatture and pressure, liquid water has maximum density than equal volume of ice and water vapour. Therefore, 15 L of water will have maximum molecules than 15 L of H2O gas and 15 L of Ice !
