← HistoryWhich outcome occurs given a Byzantine mosaic floor at high temperature?
A)Tesserae detach due thermal expansion✓
B)Substrate cools through convection alone
C)Grout becomes more chemically inert
D)Entire area converts incident radiation efficiently
💡 Explanation
Tesserae detach due to thermal expansion, therefore the mechanical stress overcomes the adhesive strength, because differential heating causes varied expansion rates among the mosaic components, rather than convection dominated transfer of heat being localized to the substrate.
