The temperature in an oven does not rise exponentially; instead, it rises linearly until it reaches the set temperature. When you turn on an oven, it gradually heats up until it reaches the desired temperature. During this time, the temperature increase follows a linear pattern.
For example, if you set your oven to 350 degrees Fahrenheit (176.67 degrees Celsius) and the initial temperature is room temperature (let's say 70 degrees Fahrenheit or 21.11 degrees Celsius), the oven's temperature will increase at a relatively constant rate until it reaches 350 degrees Fahrenheit. This linear rise means that the temperature increase is consistent over time.
However, once the oven reaches the set temperature, it will try to maintain that temperature, leading to fluctuations that might appear as slight curves or small oscillations around the desired temperature point. These fluctuations are normal and are part of the oven's temperature control system trying to keep the oven at the set temperature.
In summary, the temperature in an oven rises linearly from its initial state to the set temperature, and then it fluctuates slightly around that set temperature to maintain the desired cooking conditions. It does not rise exponentially throughout the heating process.
