In an experiment, a sample of CO2 gas was shown to effuse through a pinhole at a rate of 0.033 mol/min (where 1 min = 60 s). Using the same setup, 0.033 mol of a mystery gas effused through the same pinhole in 104 seconds.

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
