How do you remove caffeine from a mixture?
Caffeine is removed in factories using super critical fluid extraction. That uses carbon dioxide under pressure (as a liquid) to pull the caffeine out, which can then be evaporated off. Caffeine can be extracted in an laboratory by adjusting to the right pH, followed by extraction with an organic solvent like hexane.
Bone and tendons for transplant are decontaminted by what?
super critical fluids
What is liquid carbonate?
Liquid carbon dioxide will only form under pressures that are above 5.1atm. Liquid carbon dioxide is used in the super critical drying of food and technological products, preparation for specimans, that are to be scanned in electron microscopy as well as the decaffeination of coffee beans.
Is there such a thing as green dry cleaning?
Yes, there is such a thing as green dry cleaning. Green dry cleaning works by using super-critical CO2 instead of volatile organic solvents to clean clothing. The super-critical CO2 is in a phase of matter that is somewhere between a liquid and a gas, this allows the clothing to be effectively cleaned without using a more harmful organic solvent. Apparently so. There is a special cleaning process that uses liquid carbon dioxide to clean clothes in an eco-friendly way.
Create an object that is both liquid and solid?
Glass is considered a super cooled liquid.

What is a good alternative to hexane?
Super critical carbon dioxide is my favorite but one can use ethanol propane and enzymatic aqueous extractions as well as mechanical press extraction.
Why super conductor is not used?
b'coz super conductivity is achieved only when the material is cooled below a critical temperature. if it cooled above the critical temp. than the material ceases to be a super conductor. to maintain it conductivity helium and liquid nitrogen which is not easy 2 be used that is why super conductor can't be used for commercial purposes in our day to day life
Is jam a solid?
I would say that jam should be considered in a state similar to a fluid at super critical conditions -where the critical fluid is showing both gas and liquid properties. What I'm saying is that it is neither a solid or liquid but shows both properties - in a sense jam doesn't know what it wants to be! The simple response would be yes it is a, very very very viscous, liquid. Thanks, Jamie.

What are critical and super critical boilers?
critical boiler operating steam parameter 221.12bar and 375 centigrate . you can rise in pressure and temperatureabove the critical point. that is called supercritical boiler.

How gas become a liquid?
When you put gas in a super freezing place, it becomes liquid.

Is there a word for the meaning a liquid below freezing point without solidification?
super-cooled liquid
