regelation meaning
ENWRegelation
- Regelation is the phenomenon of melting under pressure and freezing again when the pressure is reduced. Many sources state that regelation can be demonstrated by looping a fine wire around a block of ice, with a heavy weight attached to it.
- If 1 mm diameter wire is used, over an ice cube 50 mm wide, the area the force is exerted on is 50 mm2. This is 50×10−6 m2.
- Force (in newtons) equals pressure (in pascals) multiplied by area (in square metres).
- If at least 500 atm (50 MPa) is required to melt the ice, a force of (50×106 Pa)(50×10−6 m2) = 2500 N is required, a force roughly equal to the weight of 250 kg on Earth.
