According to the Wikipedia article, a non-mathematical explanation of Newton's Law of Cooling is: "The rate of heat loss of a body is proportional to the temperature difference between the body and its surroundings."
In other words, it is assumed that the rate of heat loss will increase linearly with temperature. This is basically correct if you consider only conduction; however, in the case of radiation, the radiation emitted by a body is proportional to the fourth power of the absolute temperature (for example, temperature measured in Kelvin). This will give you a curve, not a straight line; for small temperature intervals, you can approximate this with a straight line, but it will not be exact.

What produces high temperature refrigeration?
an air conditioning system, is considered high-temperature refrigeration and is used for comfort cooling.
Is Boyle law valid at very high temperature?
Yes, if the pressure is low.
Is the boyles law is valid at high temperature?
Yes, if the pressure is low.
How does a thermostat regulate heating and cooling in a home?
A thermostat regulates heating and cooling in a home by sensing the temperature and comparing it to the desired temperature set by the user. When the temperature is too high, the thermostat signals the heating system to turn on. When the temperature is too low, the thermostat signals the cooling system to turn on. This process helps maintain a comfortable temperature in the home.
Why dodge stratus cooling fans working even after engine is shut down?
Cooling fans are controlled by the computer based on input from temperature sensor. After the vehicle is shut down, if the temperature is still high, the computer will turn on the fans to cool the engine.
Which system cooling equipment is best for a desktop that runs at high temperatures?
The system cooling equipment that is best for a desktop computer that runs on high temperatures would be one that equally distributes the cool air as to maintain the temperature and the performance of the desktop .
What changes a high pressure vapor to a high pressure liquid?
Cooling the high pressure vapor to lower its temperature and increase its density can cause it to condense and change into a high pressure liquid.
How is the intake air heated to such a high temperature?
It is heated to such a high temperature by going over the engine which is really hot and is part of the cooling system, the cold air goes over some part of the engine and comes out hot. It is part of the cooling system of a car, so therefor if your car has overheating problems turn the heater on.
How does a thermostat regulate the temperature for both heating and cooling in a building?
A thermostat regulates the temperature in a building by sensing the current temperature and comparing it to the desired temperature set by the user. When the temperature is too high, the thermostat signals the heating system to turn on and warm the building. Conversely, when the temperature is too low, the thermostat signals the cooling system to turn on and cool the building. This process continues until the desired temperature is reached and maintained.
Cooling fan to run when car is off?
If the temperature of your car engine is still very high after stopping, the car cooling fan will continue to run, and the cooling fan will not work until the temperature drops.The above answer comes from Suzhou Santian Precision Mould Manufacturing Co., Ltd.
When was Newton South High School created?
Newton South High School was created in 1960.
