A sample of CO2 and a sample of H2 contain the same number of particles at STP. If the CO2 sample has been measured at 20mL, what volume must the H2 occupy in milliliters?

We can’t you if you only tell us that you have to show us what the answers are

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
