Paddle boats are boats that are propelled by a paddle wheel using similar mechanics as a water wheel. A water wheel is propelled by flowing water. A paddle boat can be operated using human power, a steam engine, or solar power. Describe the energy transfers and transformations that take place within the paddle wheel system.

Gallium melts near room temperature and has one of the largest  liquid  ranges of any metal, so it has found use in high temperature thermometers.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.

They are all solids.
