heated above 50C for more than 2 minutes. On
the other hand, the temperature of the adhesive should not exceed 120 C. Otherwise it is
unusable. If we consider the material Z and subfloor have 25C of initial temperature, how long
will it take to lift up material Z? Also, what will be the temperature of the adhesive after this
tìme period? Assume that the subfloor and material Z have the same k =0,15 W/mK and p.cs
