PERUUS A metal has an initial oxide coating thickness, y, of 60 nm. After 2 hours at 700°C the oxide has grown to a thickness of 80 nm. Assuming a parabolic growth rate law applies, i.e. y² = c t + d (where, t is the time in hours and both c and d are constants) what will be the approximate thickness of the coating after a total of 36 hours at 700°C? 210 nm. 116 nm.
