The intensity of sound at a construction site is 0.10 W/m^2. If the area of the eardrum is 0.20 cm^2, how much sound energy is absorbed by one ear in an 8-h workday? Represent mathematically the intensity I of the sound, the area of the eardrum, and the time interval

Which changes of state do the labels represent? a: b: c:
