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 human small intestine has a surface area about ten times greater than the skin surface. The large intestine is wide in diameters but shorter than the small intestine. It is only about 1.5 meters (5 feet) long. There is no decomposition of food in the large intestine.he small intestine of a human can be as long as six to eight meters long, depending on age and size of being. So much length can be compacted into so little space because of the nature of the small intestine; it is coiled and takes up less space, while maintaining it's enormous surface area.
