Me i beg you i relly need it urgent 15 points!

The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat.  All computers need a fan to prevent them over-heating for this very reason.  Therefore heat is lost and energy is wasted.

Another example is a lightbulb.  When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.

These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)

False. records show otherwise
