g The Jar test is implemented as a venue to identify the optimum coagulant dose for Alum (as decsribed in section 6-2 of the textbook. The Jar Test identifies the optimum alum dose as 25 mg/L. Determine the alkalinity of the raw water (before alum addition) if the water maintains an alkalinity as 45 mg/L as CaCO3 after sedimentation of the solids.

Exothermic,  physical change after it is already baked

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
