A balloon contains Helium, Neon, Argon, and Krypton gases. The pressure of the balloon is 1000 kPa. The following pressures are known: PHe = 350 kPa, PNe = 220 kPa, and PAr = 70 kPa. Determine the pressure of krypton in the balloon.

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
