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.
It is a myth that the intestines from one person can stretch around the world. The circumference of the Earth is about 24,901 miles. Since the average adult intestines stretch about 25 feet, it would take 211.2 human intestines to span one mile. This means that it would take the intestines of 5,259,091.2 average adults to stretch around the entire world.
