Knowledge of chemistry allows the public to make informed decisions
Q=mc(change in temp)
Q is amount of heat, m is mass, c is specific heat
Water:
Q= (50.0g)(4.18 J/g°C)(63°C)
Q= 13167J
Aluminum:
Q= (200.0g)(0.900 J/g°C)(63°C)
Q= 11340J
Water requires more heat
Matter that has a uniform and definite composition is called a vapor
When a conductor is passed through a magnetic field, a current is induced in the conductor. This phenomenon is called electromagnetic induction. A changing magnetic field creates an electric field or current. This happens because of the movement of electrons in conductor as affected by the presence of the changing magnetic field.
