How much energy is gained by copper when 48.7 g of copper is warmed from 10.2 c? the specific heat capacity of copper is 0.385 j/(gxc)?

Answer : The energy gained by copper can be calculated by using the below formula :

Energy = Mass X Specific heat X Temperature change.

Solution : Given, Mass of Cu = 48.7
 Specific heat = 0.385
Temperature change = 10 to x = (x-10)

On substituting the values we get,

Energy = 48.7 X 0.385 X (x-10) = 18.7495 X (x-10)  KJ

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
