Which of the following is a chemical change? a water vapor in the air turns to liquid water in the form of rain b the oxygen in the air forms ozone in presence of uv rays c dust and soot particles being suspended in the air d sulphur dioxide being released in the air

I think that it’s A i have done a test on this before so I think it’s A

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

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
