The liquid phase of matter has no definite shape but it has a definite volume. Liquids have no definite shape because the particles in a liquid are able to change position.

An introduction to superfluid project
- 1. An Introduction To SuperFluid By: Hossein Rahmani (rahmanihossain85@yahoo.com)
- 2. A liquid with zero viscosity???????!!!!!!!!!
- 3. A SUBSTANCE WITH LIQUID STATE NEAR ABSOLUTE ZERO TEMPERATURE????!!!!
- 6. SOLIDS THE SOLID PHASE OF MATTER HAS A DEFINITE SHAPE AND VOLUME. THE PARTICLES IN A SOLID ARE TIGHTLY PACKED TOGETHER AND CANNOT CHANGE POSITION EASILY, THEY ONLY VIBRATE.
- 7. EXAMPLES OF SOLIDS • ROCK • WINDOW • DESK • APPLE • PEN
- 8. LIQUID THE LIQUID PHASE OF MATTER HAS NO DEFINITE SHAPE BUT IT HAS A DEFINITE VOLUME. LIQUIDS HAVE NO DEFINITE SHAPE BECAUSE THE PARTICLES IN A LIQUID ARE ABLE TO CHANGE POSITION AND SLIDE PAST ONE ANOTHER.
- 9. EXAMPLES OF LIQUIDS• WATER • DISH SOAP • BUBBLE SOLUTION • LAUNDRY DETERGENT • MERCURY
- 10. GAS THE GAS PHASE OF MATTER HAS NO DEFINITE SHAPE OR VOLUME. THE PARTICLES IN A GAS ARE ALWAYS IN MOTION AND THEY CAN MOVE FREELY TO ALL PARTS OF A CONTAINER.
- 11. EXAMPLES OF GASES • AIR • OXYGEN • NEON • RADON
- 12. PLASMA THE PLASMA PHASE OF MATTER IS SIMILAR TO THE GAS PHASE BUT EXISTS IN ONLY VERY HIGH TEMPERATURES AND PRESSURES AND IS VERY RARE.
- 13. EXAMPLES OF PLASMA • AURORAS • LIGHTNING • STARS
- 14. BOSE-EINSTEIN CONDENSATE PHASE A BOSE-EINSTEIN CONDENSATE IS A GASEOUS SUPER- FLUID PHASE FORMED BY PARTICLES COOLED TO VERY LOW TEMPERATURES VERY NEAR TO ABSOLUTE ZERO.
- 15. BOSE-EINSTEIN CONDENSATE PHASE SUPERCONDUCTORS SUPERFLUIDS Normal Liquid, (He I) Superfluid (He II) Solid
- 16. LAMBDA POINT?
- 17. CLASSIC MECHANIC QUANTUM MECHANIC vs
- 18. DEFINITION OF THE SUPERFLUID STATE AS PER WIKIPEDIA: 'SUPERFLUID' IS A STATE OF MATTER IN WHICH THE MATTER BEHAVES LIKE A FLUID WITHOUT VISCOSITY AND WITH EXTREMELY HIGH THERMAL CONDUCTIVITY.
- 19. Helium
- 20. Gearbox modeling
- 21. Features: 1.Flow without viscosity 2.Rising up the sides of its containers 3.With zero entropy 4.With high conductivity 5.Fountain effect
- 22. ATTRIBUTES OF THE SUPERFLUID STATE
- 23. VISCOSITY follow the movement of their neighbors
- 24. ENTROPY / HEAT CAPACITY IN A SUPERFLUID STATE, THE INDIVIDUAL ATOMS ARE MAGNETICALLY CHAINED TO EACH OTHER, AS A CONSEQUENCE OF WHICH THE INDIVIDUAL ATOMS CAN NO LONGER MOVE INDEPENDENT FROM EACH OTHER. THEREFORE THE HEAT CAPACITY OF THE SUPERFLUID FRACTION DROPS.
- 25. THERMAL CONDUCTIVITY / STILL BOILING • MAGNETIC COUPLING • SECOND SOUND • NO TEMPERATURE GRADIENT
- 26. ESCAPE THROUGH PORES IN A CONTAINER • NOT GET THE OPPORTUNITY TO GET STUCK • CONTINUES VIBRATIONS • FOLLOW THE LEADERS
- 27. VORTEX LINES / RINGS • BEHAVE LIKE A SINGLE OBJECT • CORIOLIS EFFECT • ENERGY IS EXPRESSED AS STATIC WAVES
- 28. Application: 1.Orientation of the spacecraft 2.Earthquake prediction 3.Measuring the exact velocity of Earth's rotation
- 30. THE END
