Which are Essentially Equivalent Treatments

Question

Which are essentially equivalent treatments?
A)dry 200°C heat for 1.5 hours; wet 121°C heat for 15 minutes
B)dry 160°C heat for 1.0 hour; wet 200°C heat for 30 minutes
C)dry 121°C heat for 1.5 hours; wet 200°C heat for 15 minutes
D)dry 100°C heat for 2.0 hours; wet 100°C heat for 30 minutes

Accepted Answer

The equivalent treatments are those that use the same amount of heat over time to achieve the same results. Option A and C both use 200°C heat, but the time for option A (1.5 hours) is equivalent to the time for wet heat in option C (15 minutes). Additionally, option A uses dry heat, whereas option C uses wet heat, but this difference in the type of heat doesn't change their equivalency. Options B and D do not use the same amount of heat over time, so they are not equivalent to option A.
