Water is one of the agents of deterioration. Its effects can be seen in these flood-damaged library books. The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects (such as collections held by galleries, libraries, archives and museums).

Water carries heat away far more effectively than air. Evaporative cooling on the surface is also an effective mechanism of heat loss, and can affect divers in wet diving suits while travelling on boats. [46] Diving suits are available that are suited to a wide range of water temperature down to freezing. [47]
Water can come from roofs leaking during rainstorms, floods, fire sprinkler systems, or broken pipes. [7] It can soften and destroy the bone, antler, or horn if it becomes waterlogged. Mold and mildew growth can cause further damage. If the water in the crevices or pores of the bone, antler, or horn were to freeze, it would crack the object.
“The title of fastest punch in the animal kingdom firmly belongs to the peacock mantis shrimp, whose club-like appendages reach the speed of a .22-caliber slug, shatter clamshells with ease and ...
The diver may not notice a gradual change in inlet temperature, and in the early stages of hypo- or hyperthermia, may not notice the deteriorating condition. [27] The suit is loose fitting to allow unimpeded water flow. This causes a large volume of water (13 to 22 litres) to be held in the suit, which can impede swimming due to the added inertia.
Bones are the framework of our bodies and make up our skeletal system.But they aren’t indestructible and they can sometimes break. Scripps News went to an expert to find out why. "Bones break ...
The cold water can also cause heart attack due to vasoconstriction; [4] the heart has to work harder to pump the same volume of blood throughout the body, and for people with heart disease, this additional workload can cause the heart to go into arrest. A person who survives the initial minute of trauma after falling into icy water can survive ...
When the temperature drops below 20 degrees Fahrenheit, run a drip from the faucets. Even just a trickle of cold water can help. Don’t forget to close your garage door.
