3. what is the change in temperature when 30g of water is heated
and releases 2130 cal of heat? the specific heat of water is 1.0
cal/g°c.

100%sorry if i’m wronghope this good luck: )

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

I’m not sure about this question
