Melting point: Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
Overall, in humans, the large intestine is about 1.5 metres (5 ft) long, which is about one-fifth of the whole length of the gastrointestinal tract.
The large intestine, or colon, is about six feet long. It reabsorbs water from the undigested food passed on from the small intestine. A meal usually stays in your stomach for around three hours, but can stay in your digestive system for up to three days. The small intestine is about 6 meters (20 feet) long.
