Where does the energy come from which makes the pipes at the back of a fridge warm?
The energy comes from the heat taken from the heat/energy inside of the refrigerator/fridge. A fridge takes heat energy from inside the fridge and dumps it outside the fridge into the the pipes on the back of the fridge and into the room.
What are the main uses for thermal energy?
Thermal energy is used to keep us warm. An example of a use of thermal energy is a radiator. This is because a radiator is used to warm a room and keep people warm.
Why is fridge cold inside but warm outside?
It is cold inside because thermal energy gets trapped outside because of the particle theory.
The pipes behind a fridge are warm where does the energy come from to warm these pipes?
Ammonia gas is compressed until it becomes very hot from the increased pressure. This heated gas flows through the coils behind the refrigerator, which allow excess heat to be released into the surrounding air.
What will happen if you leave a refrigerator door open in a room?
The room will warm up.The fridge with the door left open will run pretty much continuously to try to cool the inside. Our fridge doesn't know the door is open, so it keeps running. The thermostat inside never senses that the inside has cooled, so it tells the compressor to stay on. The room will be cooled by the fridge, but remember that the compressor dumps heat out into the room all the while that it's running. And because the fridge is not 100% efficient, there will be more heat generated than there will be cooling. The result? The room will eventually warm up.I would disagree partially with the above answer. 1) Efficiency is a term not really used for refrigerators. The term coefficient of performance is used because it can be and usually is greater than one (or greater than 100% in other words) and equals the heat removed from the inside of the fridge divided by the work input. 2) Now, if a perfect fridge was running on a Carnot cycle (no friction in the parts and other criteria) that gives the most cooling for the least amount of work, the room would still heat up as governed by the first law of thermodynamics. W=Heat from the condenser - heat from the evaporator or W+QL=QH. In this case all the terms are considered to be positive numbers. Clearly QH>QL which means the room is getting warmer.Probably the easiest was to understand this is that work is going into the insulated room which means the overall energy and therefore temperature is going up.

Why does a refrigerator warm a room?
If you feel behind a fridge, you will feel the warm air. This warmth is from the inside of the fridge as the inside is cooled, and from the pump.
Will mousse get too soft if left out of the fridge?
Yes, if the mousse sits outside of the fridge it will get too soft. It will also lose more physical properties if the room is warm.
If you heat with electric heat does it cost you more to leave the refrigerator door open during the winter since any lost energy goes into heat anyway?
The energy you put into running the fridge, which is that required to run the compressor, will in any case appear in the room where the fridge is situated, so if this room is in the house and not in an unheated outhouse where this energy would be lost, this energy goes towards the total you need to keep the house warm. You probably have noticed that the heat exchanger on the back of the fridge gets warm, and in fact it's best to allow some air to circulate behind the fridge to take this heat away by convection, so it does add to the heating in that room. If you leave the fridge door open, the compressor will need to run overtime, maybe even continuously, so you use more electricity for the fridge but this will help to heat the room. However the purpose of the fridge is to keep the contents cool, and with the door open you will get temperature gradients that mean part of the contents is not at the desired cold temperature, so it's not a good idea! A somewhat similar argument can be made when using low energy light bulbs instead of normal ones. You put less energy into the lighting, but that must mean you need more energy from the heating system.
Can you put a warm turkey in fridge after cooking?
No. It is adviseable to cool it at room temperature before putting it in the refrigerator.However if you put a hot turkey in a refrigerator it will use up more energy /cooling in the refrigerator.
Where has the energy come from to warm the pipes at the back of a fridge?
A significant portion of it is the heat that was removed from the groceries inside.
Can you leave bread dough in the fridge and use it in the morning?
Yes, but you have to let it warm to room temperature and rise before baking.

Thermal energy is used to keep us warm. An example of a use of thermal energy is a radiator. This is because a radiator is used to warm a room and keep people warm.
Do you cool a pumpkin pie to room temperature before refrigerating it?
Yes, otherwise you might warm up the fridge too much.
Explain how a radiator in a room is able to warm the whole room?
warm air particles slowly pass heat energy to all the other air particles
What happens to the average energy of the particles in milk when the milk is taken from the refrigerator and begins to warm up?
the average energy of the particles in the milk goes up and the particles move faster when it is removed from the fridge and begins to warm up.
Why does carbonated beverages maintain more carbonation when refrigerated that at room temperature when opened?
they should keep the frizz longer is stored in the fridge...
