the temperature of a chemical reaction oscillates between a low of 25 degree celcius and a high 140 degree Celcius. the temperature is at its lowest point at time t=0 , and reaches its maximum point over a one-hour period. it then takes the same amount of time to return back to its initial temperature. let y = H(t) denote the temperature of the reaction hours after the reaction begins. what is the period of the function ?

Final answer:

The period of the temperature function for the chemical reaction, which oscillates between 25 degrees Celsius and 140 degrees Celsius and returns to its initial temperature over a two-hour cycle, is 2 hours.

Step-by-step explanation:

The question refers to a chemical reaction whose temperature oscillates between a low of 25 degrees Celsius and a high of 140 degrees Celsius. The oscillation of temperature follows a periodic function with respect to time, denoted as y = H(t). Since the temperature reaches its peak in one hour and returns to its starting value in the next hour, the period of the function is the total time for a complete cycle of temperature change, which is 2 hours.
