if a conductivity absorbs solar matter then that wall will decrease in speck
thermal_conductivity is tangible_physical_quantity. photons has zero_rest_mass uranium_235 is weak_gamma_emitter. depleted_uranium is weak_gamma_emitter. radiation_resistance is non_aspectual_quantity. blocked_sunlight has powerful_effect_on_microclimate radiation_resistance is tangible_physical_quantity. unprocessed_uranium is weak_gamma_emitter. low_collapsible_construction_barrier is tangible_thing. if smother occurs then cover occurs.
