Depends what's in your gravel.
In order of best to worst:
Sandstone 1
Limestone
Concrete
Water
Soil

saw dust is the better termal insulator
That wire could use a better insulator.
Water does not filter particles: it is the other way around. Pebbles, gravel, and sand are used to filter water, with the smallest particle size (sand) filtering the most particulates from the water, whether it is salt water or fresh water.
It is an insulator. It would take many wraps to make it become a good insulator. There are much better products in the market place to use for insulation purposes which are much safer.
Plain distilled (or double distilled) water with no impurities is a poor conductor of electricity. The more impurities it has the better conductor it becomes
It is typically better to buy gravel dry because you are paying for the weight of the water in the gravel when purchasing it wet, which can increase the cost. Additionally, wet gravel can be heavier and harder to transport.
Non-metal
Insulator
The best gravel for drainage around a house is typically a coarse gravel with angular edges, such as crushed stone or pea gravel. These types of gravel allow for better water flow and help prevent water from pooling around the foundation of the house. It is important to choose a gravel size that is appropriate for the specific drainage needs of the area.
Polystyrene is a better insulator than water because it traps air molecules within its structure, creating a barrier to prevent heat transfer. Water, on the other hand, is a good conductor of heat and can easily transfer heat energy.
fresh water and peppels fresh water and peppels
The Gravel will absorb the water until it can absorb anymore.
pure water is an insulator.
No, it does not.
The amount of time that gravel can retain water will vary depending on its state. Fine gravel will holder water for long as opposed to coarse gravel.
saw dust is the better termal insulator
When gravel is mixed with water, the gravel will not dissolve or undergo any chemical reaction with the water. The gravel will remain suspended or settle at the bottom of the water due to differences in density. The water may become cloudy initially due to the particles of gravel being dispersed, but eventually, the gravel will settle down, leaving clear water on top.
