A student dissolves 4 g of salt into 10 g of water. The total weight of the solution is 14 g. The student then heats the solution until all of the liquid turns into a gas and only the salt is left. The student is able to collect the evaporated gas. The student weighs the salt left over from the solution and the evaporated gas. How much should the student expect the salt and vapor to weigh?

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
