The process of formation of a reddish-brown substance on the surface of the iron objects in the presence of flaky moisture and air is called rusting.
 
        
                    
             
        
        
        
Answer:
the thermistor temperature = 
Explanation:
Given that:
A thermistor is placed in a 100 °C environment and its resistance measured as 20,000 Ω. 
i.e Temperature
  
 
Resistance of the thermistor  20,000 ohms
 20,000 ohms 
Material constant  = 3650
 = 3650
Resistance of the thermistor  = 500 ohms
 = 500 ohms
Using the equation :


Taking log of both sides





Replacing our values into the above equation :






Thus, the thermistor temperature =

To solve this problem it is necessary to apply the concepts related to the Stefan-Boltzman law that is responsible for calculating radioactive energy.
Mathematically this expression can be given as

Where
A = Surface area of the Object
 Stefan-Boltzmann constant
 Stefan-Boltzmann constant 
e = Emissivity 
T = Temperature (Kelvin)
Our values are given as





Replacing at our equation and solving to find the temperature 1 we have,




Therefore the the temperature of the coldest room in which this person could stand and not experience a drop in body temperature is 12°C
