Typically, an electrical appliance uses electrical energy at a certain rate (a certain power, a certain amount of energy per second). The longer you keep it on, the more energy it will use in total. The relation is simply:
energy = power x time
Units might be joule, watt, and seconds; or kWh, kW, and seconds.

What does mechanical energy transform to?
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
What additional features do energy star appliances have in contrast with conventional appliances?

What is the relationship between appliances power rating and the amount of heat it produce?
power rating is the rate of moving energy their relationship in the amount of heat it produce it divided by time to move that much energy
Does plugging appliances into a surge protector save energy?
under normal use, no. the only time it may help is during a surge, where it blocks a large flow of power for a brief second. but this is minimal of course, you could say it saves you the energy of buying new appliances should a surge ruin them but that is stretching it :)

Is the black dwarft a star?
Sort of. It can be considered a dead star - one that no longer produces energy. At the end of their life, smaller (less massive) stars become white dwarves. These will no longer produce energy, but will continue to glow with their residual energy for a long time. After a long, long time - much longer than the current age of the Universe - they will stop emitting significant amounts of energy, and become black dwarves.
