Is it possible for one particle to be at rest after the collision? It is possible for one of the particles to be at rest after collision, provided the other particle leaves the collision with a momentum equal to the total momentum of the two-particle system before impact. If all the kinetic energy disappears, there […]

Is a cup of ice the same as a cup of water? Using the ratio, one can simply multiply the volume of the ice by 0.92, which is the conversion factor for the volume of ice to liquid water. Notice that earlier, you could have just used this ratio to quickly calculate that 1 cup […]

How will you identify a saturated solution? If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container […]

How do you find the energy of the first excited state? For hydrogen-like atoms, i.e. H , He+ , Li2+ , etc., the energy levels are given by: En=−Z2⋅13.61 eVn2. where Z is the atomic number and n is the quantum level. E2=−22⋅13.61 eV22. =−13.61 eV. E1=−22⋅13.61 eV12. =−54.44 eV. How do you find the […]
