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.
Quick Answer. The combined length of the small and large intestines averages 25 feet long. Individually, the uncoiled small intestine has an average length of 20 feet, while the large intestine has an average length of 5 feet. The length of the intestines allows for enough time for nutrients to be absorbed before waste is expelled from the body.
