Answer:
Because you can freeze the water you melted back into a ice cube.

Answer:
Yes
Explanation:
A supercritical fluid has good properties for both liquid and as for extraction properties, the advantages then include:
- The fact that it has a lower viscosity than liquid CO2 allowing it to move through and around coffee beans more thoroughly with creating back pressure
- Its density is comparable to that of liquid CO2 meaning there is much CO2 per litre as there is liquid form making it more efficient
- It has a higher diffusivity than liquid CO2 which aids with penetration of the coffee beans on a molecular level
This experiment would not work with tea leaves because they also contain caffeine
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
