When there is food in the stomach the pH can raise to as high as 4-5. After the food leaves the stomach bicarbonate ions are secreted to neutralize and alkalinize the mixture. The pH of the small intestine is approximately 8. As far as how long food stays in your stomach it depends on what that food is.

Ductility and malleability are two aspects of the plasticity of solid materials. In metals, ductility and malleability are very high due to their ability to sustain large amounts of plastic deformations within the crystal structure.Platinum is the most ductile material, and gold is the most malleable material.Ductility. Ductility is the ability of a solid material to undergo tensile stress. This property of a solid material can be measured and describes the extent to which the solid material can be plastically deformed without fracture.It is often depicted by the ability of the solid to stretch into a wire when pulled at the ends.uctility vs Malleability. In common language, ductility refers to the ability to be deformed without losing toughness; that is pliable, but not brittle. Malleable means the ability to be hammered or pressed into shape without breaking or cracking.
