What is an example of how electrical energy can be converted to another form of energy at home?
Think of any device that needs to be plugged in, or that is connected to the power network.Light-bulbs: convert electrical energy to light.Toaster: converts electrical energy to heat.Refrigerator: uses electrical energy as a heat pump (takes heat out of the inside, into the outside).Computer: uses the electrical energy in electronic circuits; eventually the energy gets converted to heat. (In other devices, the electrical energy also gets converted to heat, eventually.)Computer monitor: converts the electrical energy to light energy.Loudspeaker: converts the electrical energy to sound.Etc.
Does a motor have electrical energy in it?
An electric motor need to be supplied electricity to operate. It can be made to generate electricity if turned by an outside force when set up correctly.
Evaporation causes cooling effect Explain with examples?
when a liquid evaporates,it gives its latent heat of vaporisation.if no heat is supplied from outside this results in cooling.
Make a hypothesis state which of three insulating materials you think will keep the inside temperature of the house higher than outside temperature for the longest period of time an explain why?
thermal energy molecule
How many volts does a radio use?
That varies. Different devices are designed differently. Somewhere on outside (usually on the back) of every electrical device there should be a kind of permanent sticker stating the voltage and current it uses.
Explain why the outside cases of electric appliances ususally are made of plastic?
Plastic is a good insulator and a bad conductor of electricity, which makes it a good material to protect people from electric shocks when handling appliances. On top of that, plastics are inexpensive and easy to shape.
Can leaving electrical appliances plugged in cause fires?
No, A plugged in appliance will not cause a fire. There has to be an outside fuel source that could catch the flame.
How do you unhook a hot tub that was connected to an outside electrical outlet?
"How do you unhook a hot tub that was connected to an '''outside electrical outlet?'''" .... Just unplug it
Are plastics important for all living organisms on the Earth?
No, actually plastics are harmful to most living organisms on earth, including humans (depending upon the plastic). Plastics are a very recent invention of humans, and outside of human convenience are not needed in any way, shape or form.
What appliances have three pins and which have two pins?
Appliances and tool that only have two pin caps (plugs) are built so that they have double insulation. This means that the electrical "hot" parts can not be touched by handling the appliance or tools and the outside shell is completely insulated and isolated from the inside shell of the equipment. Equipment that require a three pin cap (plug) do not have the double insulation and isolation built into the equipment so protection from getting an electrical shock is done by grounding the equipment, that is what the third pin is. It is used strictly for grounding.
How much heat is produced by all the electrical appliances in a security office?
That depends on the "appliances" in the security office. Generally, the easiest way to determine the amount of heat given off would be to add up the total wattage of all appliances/computers/monitors... and that would be the total. The electrical energy is almost all, eventually converted to heat. For example, if all of the computers, monitors and other equipment add up to 5,000 watts of electricity, all 5,000 watts is being converted to heat. With ONE exception: if one of the devices happens to be an AC unit, and the AC unit is exhausting heat to the OUTSIDE of the security office, that would reverse some of the heat build-up.

What is the electrical charge inside and outside the cell?
The inside of a typical cell is posotive in respect to the outside. I got this out of my Biology book.
What is the difference between inside and outside electrical boxes?
An outside electrical box has a watertight in-use outlet cover so even when a cord is plugged in the outlet stays covered. That is the main difference between the outside box and inside box. An outside box also uses a ground fault circuit interrupter.
