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 else can I help you with?
Why does planetary cooling happen?
Because of the second law of thermodynamics , law of entropy. "when energy flows from a high-temperature object to a low-temperature object, the source temperature is decreased while the sink temperature is increased; hence temperature differences tend to diminish over time."
What is the average high temperature of grasslands in Celsius?
As i am a blade of grass myself i think you will find my answer is not only valid, but accurate. The average temperature of the environment me and my bretheren reside in is 7. no more, no less.
How does a sponge bath help a patient suffering from high fever?
A sponge bath can help lower a patient's body temperature by promoting evaporation and cooling of the skin. It helps reduce fever discomfort and can provide some relief while waiting for other fever-reducing treatments to take effect. Additionally, the process of gently washing and cooling the patient can have a calming and soothing effect.
If you wanted to do this experiment more accurately you could cool the liquid more slowly and measure the temperature more accurately Suggest how you could modify the equipment to accomplish these c?
To cool the liquid more slowly, you could use a controlled water bath that maintains a consistent temperature gradient, allowing for gradual cooling. Additionally, incorporating a high-precision thermometer or a data logger with temperature sensors would enable more accurate temperature measurements throughout the cooling process. Insulating the container could also help minimize heat loss to the environment, ensuring a more stable cooling rate.
How do you eliminate scavenging high temperature alarm?
A scavenging high temperature alarm can be eliminated by disconnecting the wires feeding it and removing it from the circuit. Some connections may have to be looped together to allow electricity to continue to flow properly.
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 is newton law of cooling is not valid for high temperature?
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.
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.
What mean high CDT on a carrier unit?
Mean High CDT (Cooling Design Temperature) on a carrier unit refers to the average temperature that the system is designed to maintain for optimal cooling performance. It takes into account various environmental factors and is crucial for ensuring the unit operates efficiently. This metric helps in sizing the HVAC system appropriately to meet the cooling demands of a space. Understanding the mean high CDT is essential for effective climate control and energy efficiency.
