What does the word kelvins mean when talking of temperature?
Kelvin is a temperature scale, like Fahrenheit or Centigrade. It is generally used in scientific contexts. One degree Kelvin is equal to one degree Centigrade. In order to find the temperature in Kelvin, I have provided the following equations. If you have a temperature in Fahrenheit and want to know it in Kelvin, it is easiest to convert to Centigrade first. (Fahrenheit Temperature - 32) X (5/9) = (Centigrade Temperature) If you have a Centigrade temperature and want to know it in Kelvin, you can convert it directly to Kelvin. (Centigrade Temperature + 273) = (Kelvin Temperature) The reason for the 273 is that scientists wanted the Kelvin scale to begin at Absolute Zero. Thus, Absolute Zero is 0 K and -273 degrees Centigrade. Since, as I stated above, one degree Centigrade is equal to one degree Kelvin, this equation works. If you want to convert back from Kelvin, the following equations may be used. (Kelvin Temperature -273) = (Centigrade Temperature) And if you're asked to report the temperature in Fahrenheit, use (Centigrade Temperature X (9/5)) +32 = (Fahrenheit Temperature) It should be noted that you do not include a degree symbol when you report a Kelvin temperature.
What is absolute zero and why is it important?
Absolute zero is the temperature of outer space. It is the lowest temperature matter can reach. It is -273.15 on the Celsius scale and 0.0 on the Kelvin scale. There is still a type of energy, known as zero point energy, the energy of outer space, left at 0.0 Kelvin, but this energy cannot be used. Work cannot be obtained from things at 0.0 Kelvin, because there is no lower temperature to which the energy might flow. The entropy of anything at 0.0 Kelvin is maximum, meaning no work can be obtained from it. (Entropy is reverse of what we are perhaps used to: minimum means lots of work can be extracted which causes the entropy to INCREASE until the entropy is maximum and no further energy can be extracted..) There are laws of physics which only agree with reality when the Kelvin scale is used. For example, the ideal gas law is PV = NRT. The pressure times the volume of an ideal gas is the product of the number of moles of gas (N) times a constant (R) times the temperature. This equation only works of the temperature is in Kelvin (the units of the Kelvin scale are Kelvin, not degree). The equation for the power radiated from a hot object only works if the temperature is Kelvin. In fact, much of physics only works when you use the Kelvin scale for temperature.
How can you tell the temperature in a weather system?
A thermometer works well for this.
What stops force?
An immovable concrete wall works pretty good for me.Theoretically it is said that Zero Kelvin (absolute zero) is the temperature at which no movement of particles/molecules is possible. Zero Kelvin in Celsius is -273.15 degrees. In Fahrenheit it is -459.67 degrees.
How anti lock brake system works?

How incubator works?
Incubators are used in Biology, hospitals, and agriculture for hatching eggs. An incubator has a thermostat that is turned on to a specific temperature and when the temperature goes below the set temperature, the heating element comes on.
How does a thermostatic switch works?
A thermostatic switch works by turning on when the temperature is below a certain point. A thermostatic switch will also turn off when the temperature reaches a certain point. Thermostatic switches are used for space heaters so that they do not overheat.
Does the 2002 Ford Expedition have the LATCH system?
I believe the 2003 - and newer have the LATCH System. Check related link below... How the LATCH System Works on Car Seats
How does a predator drone works?
Some of that information is classified. See the related link, below, for details on this weapon system.
Why most heat produced by heat engines are tranffered to the environment?
According to the theory of heat engines (read about "Carnot cycle" for more details), heat can not be converted 100% to other forms of energy. The remaining energy gets transferred from the "reservoir" of higher temperature, to the "reservoir" of lower temperature. The latter would be the environment. For example, if the heat engine works at 600 Kelvin, and the environment has a temperature of 300 Kelvin, in theory half the heat of the higher-temperature reservoir can be used. However, real engines have a lower efficiency than the theoretical maximum according to Carnot.
How is your endocrine system like the thermostat in your house?
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again.
Describe a negative feedback system?
Q: describe the negative- feedback system subject: Science A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system. example: it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream. ur wlcm (: SnazzyChazzy <33
