Does your body absorb salt water from the ocean when you swim in it?
No, your body does not absorb salt water from the ocean when you swim in it.
Where water is absorb?

What do plants absorb through their roots?
Plants absorb water and nutrients through their roots.
How do baobab trees absorb water?
Baobab trees have extensive root systems that spread out to absorb water from the ground. They can store large amounts of water in their trunk and branches to survive long periods of drought. They are adapted to arid environments, so they are efficient at extracting water from the soil.
What do plants absorb through their root systems?
Plants absorb water, nutrients, and minerals through their root systems.
What difficulties arise in use of aggregate which absorb water?

What difficulties arise in the use of aggregates which absorb water How theyovercome (a) in the laboratory and (b) on the job?
When using aggregates that absorb water, several difficulties can arise. These difficulties include: Increased water demand: Aggregates that absorb water can increase the water demand in a concrete mix. This can lead to challenges in achieving the desired water-cement ratio and can affect the strength and durability of the concrete. Reduced workability: The absorption of water by aggregates can reduce the workability of the concrete, making it more difficult to place and finish. This can result in issues such as segregation, poor compaction, and difficulty in achieving the desired surface finish. To overcome these difficulties, the following approaches can be taken: (a) In the laboratory: Pre-wetting aggregates: One way to overcome the increased water demand and reduced workability is to pre-wet the aggregates before mixing them with cement and other ingredients. This ensures that the absorbed water in the aggregates is taken into account during the mix design process. It helps maintain the desired water-cement ratio and improves workability. Adjusting mix proportions: The mix proportions can be adjusted by considering the absorption characteristics of the aggregates. By accounting for the water absorption capacity of the aggregates, the required water content can be determined to achieve the desired consistency and workability. (b) On the job: Proper storage and handling: Aggregates should be stored in covered areas or protected from rainwater to prevent additional water absorption. Proper handling practices during transportation and on-site storage can help minimize the absorption of water by aggregates. Moisture control: On-site, measures can be taken to control moisture levels. For example, if the aggregates are excessively dry, they can be sprayed with water to ensure they have the right moisture content before mixing. Conversely, if the aggregates are already saturated, adjustments can be made to the mix design to compensate for the absorbed water. By implementing these strategies, the difficulties associated with the use of aggregates that absorb water can be mitigated, ensuring better concrete performance both in the laboratory and on the job.
How coarse aggregate shape affect workability?
Aggregates with angular particles are more difficulties to compact than one with rounded particles and therefor,requires more water in the mix to act as alubricant.this additional water, on evaporation ,tends to leave void spaces in the hardened concrete made with rounded aggregates particles which requires less water for compaction.the nature of the particles of an aggregates will also affect workability.(
What are the ingredient of concrete?

What difficulties would arise if the US had to depend on water frozen in the polar icecaps for its water needs?
Some difficulties that could arise include the high cost and energy required to transport the frozen water from the polar icecaps to the US, the environmental impact of extracting water from these sensitive ecosystems, and potential geopolitical tensions over control and access to this valuable resource. Additionally, the logistics of storing and distributing frozen water on such a large scale would pose significant challenges.

What happens to soil when you pour water on it?
When you pour water on soil, it will initially absorb the water. If the soil is already saturated, excess water will run off or seep deeper into the ground. Water helps to form aggregates in the soil, making it more stable and conducive for plant growth.
What are the main ingredients of concrete?
cement aggregates water
What are the thre main ingredients of concrete?

When does hydration in concrete start?
As soon as the Cement comes into contact with water. This will start as soon as the cement and aggregates come into contact unless the aggregates have been dried of all surface water.
What will happen when gravel touches water?
The Gravel will absorb the water until it can absorb anymore.
What is coarse aggregates?
Raw materials that are a component in concrete, aggregates are inert granular materials such as sand, gravel or crushed stone. Coarse aggregates are particles greater than 4.75mm, but they generally range between 9.5mm to 37.5mm in diameter. Primary coarse aggregates come from the land or water. Secondary aggregates are the by-products of extractive operations. The third source coarse aggregates come from is recycled aggregate, which is sand, and recycled concrete aggregate.
