The temperature of a chemical reaction oscillates between a low of 40 degrees C and a high of 100 degrees C. The temperature is at its lowest point when t = 0 and completes one cycle over a five-hour period.

(a) Sketch below the temperature, T, against the elapsed time, t, over a ten-hour period.

(b) Find the period, the amplitude, and the midline of the graph you drew in part (a).

Period is hours.

Amplitude is ___ degrees C.

Midline is T = ___ degrees C.
