Some materials in which, under certain conditions, the electrical resistance approaches zero.

A mechanical device that uses wire loops rotating in a magnetic field to produce electromagnetic induction in order to generate electricity.

A 200.0 gram sample of water at 20.0 degrees C is heated to steam at 125.0 degrees C. How much heat was absorbed? The specific heat (c) for water is 1.00 cal/gC0. The specific heat for steam is 0.480 cal/gC0. The latent heat of vaporization for water is 540.0 cal/g.

The form of heat transfer that sometimes involves energy traveling through space is known as what?

A power plant generator produces a 220 V, 35.0 A alternating current that is fed to a step-up transformer before transmission over the high lines. The transformer has a ratio of 200 to 1 wire loops. What is the voltage of the transmitted power?

Absolute zero has what numerical value on the Celsius scale?

The phase change of a solid directly into a vapor or gas.

Which form of heat flow involves large scale displacement of groups of molecules?
