LED televisions are LCD televisions. The backlighting may be LED but the image generation is performed by an LCD panel. Cold cathode fluorescent tubes are the alternative to LED lighting and they tend to generate more heat than LED.

It is quite normal for both televisions to get warm. The temperature they reach depends largely on the ventilation they have. An enclosed space will result in the television becoming much warmer than a television in open space.

If you have a problem with temperature, look at the environment before considering a new television. If necessary, think about some small equipment cooling fans to move the warm air away from the television. They can be bought very cheaply, run quietly and are usually straightforward to fit. You may also want to consult a home theater professional for specific advice on your installation.

What is the highest temperature it will get summer 2010?

It is impossible to know this, especially any specific temperature. The best that long-range forecasters can do a couple months in advance is to give an idea of weather it will be a warm or cooler than normal temperature. A high temperature can hardly even be predicted a day in advance.

Is 97.8 F a normal temperature?

The normal temperature is 98.6o Fahrenheit (37o Celsius) But 97.3o is not uncommon and is completely normal to have as a body temperature. 97o-99o is considered a normal, and safe temperature range for humans.


Is 37.1 vaginal temperature normal?

I don't know the normal but if enough people write what theirs was, when checked recently, we can estimate. Mine was 100.4, which is what is normal rectally.


How do a cooler know how to keep hot food hot and cold food cold?

Coolers are equipped with a very elegant temperature regulation mechanism. A thermocouple implanted in the cooler insulation detects temperature gradients between the interior and exterior surfaces of the cooler. If the initial gradient is measured to be rising in temperature toward the center of the cooler, the cooler insulation automatically orients itself to reflect heat back toward the center of the cooler, thereby keeping the contents warm. Conversely, if the temperature gradient detects that the contents of the cooler are cold, the insulation reverses its orientation to deflect exterior heat and preserve the colder temperatures on the inside of the cooler. All of this is accomplished through the use of a non-newtonian polymer embedded with thermo-sensitive alloys which alter their magnetic polarity to align with termperature gradients. As the temperature gradient changes so does the magnetic polarity which alters the insulation alignment in the appropriate direction. A competing theory is that coolers do not "know" to keep food hot or cold, rather they are insulated and there-by stablilize the temperature and prevent it from changing. If you place hot items in an insulated container they will stay hot, cold items will stay cold.


How many btu's in office water-cooler?

There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water
