Dry water and Burning ice: all about gas hydrates

TL;DR

Dry water is a material made up of water droplets dispersed in a hydrophobic substance, while flammable ice cubes are gas hydrates formed by mixing gas with water and lowering the temperature and raising the pressure.

Transcript

today on Applied Science we're going to talk about two unusual materials dry water and flammable ice cubes and these are both somewhat joke names but they're both very real things and we're going to take a look at the properties today let's start with the dry water this isn't a name that I came up with if you search the internet for it you'll find ...

Questions & Answers

Q: What is dry water and how is it created?

Dry water is a material made up of water droplets dispersed in a hydrophobic substance, such as hydrophobic fumed silica. It is created by blending water and the hydrophobic substance together in a blender, forming tiny water droplets coated with the hydrophobic material.

Q: What are the applications of dry water?

One proposed application for dry water is as a gas storage mechanism, potentially replacing the need for compressing and liquefying natural gas for transportation. However, further research is needed to determine its feasibility.

Q: How are flammable ice cubes formed?

Flammable ice cubes, or gas hydrates, are formed by mixing gas with water under specific temperature and pressure conditions. This results in the formation of a new material with its own crystal structure, similar in appearance to ice but containing trapped gas molecules.

Q: What are the potential uses of gas hydrates?

Gas hydrates have garnered interest from the petroleum industry due to their presence on the ocean floor and their potential as a vast source of natural gas. They are also being studied for their potential use as fuel and gas storage.

Summary & Key Takeaways

• Dry water is made up of water droplets dispersed in a hydrophobic substance, effectively creating a material that is dry to the touch.

• Flammable ice cubes, or gas hydrates, are formed by mixing gas with water under specific temperature and pressure conditions.

• Gas hydrates are commonly found on the ocean floor and are of interest to the petroleum industry, while dry water has potential applications as a gas storage mechanism.
