For the transformation of Cu described in question 1, if nucleation were to instead occur on an internal structural inhomogeneity with a wetting angle of 45°, what would be the required undercooling to maintain an identical nucleation rate to solid Cu homogeneously nucleating at an undercooling of 200 o C?

The answer is 3,5g co

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
