A wall has an inside temperature 149 Celsius and outside temperature 22 Celsius. Its area is 6 m^2 and its uniform thickness is .38m. What is the temperature gradient from inside to outside? If the inside temperature decreased, thereby increasing the temperature difference by a factor of 1.749 what would be the temperature gradient?
Temperature gradient is the rate of change of temperature with distance in any given direction at any point.
In five lines, the problem is explained and solved.
