caption: the physical characteristics of a dynamic phenomena
exif: {"Image DocumentName": "Dynamic phenomenaThe diffusion time of moisture into paper is proportional to basis weight squared for relatively high basis weight paper.", "Image ImageDescription": "The diffusion time is proportional to basis weight for low basis weight paper. This is characteristic of boundary layer formation at the sheet surface. In the boundary layer, the local humidity and temperature differ from the ambient conditions. The heat of sorption governs the conditions in the boundary layer.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
