Gas makes things buoyant, why ? And what are ways that this could be useful?
ryzh [129]

Answer:

Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.

Gas Buoyancy is useful in the following ways;

• Airships

• Steel ships and

• All floating and flying vessels

Explanation:

Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.

It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

The principle explains the reason why objects float and fly.

So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.

This is where the use of a gas comes into play.

Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.

This is what causes objects to float or fly

Homeostasis and thermoregulation

When temperatures are too low, these processes may be disrupted, which can lead to cellular damage and even death. Homoeothermic endotherms, such as bears, bats, and birds, regulate their body temperature by generating heat internally.

Temka [501]
<span>Joints with no movement are called immoveable or fibrous joints.They are also called synathrosis, they are only separated by a thin layer of fibrous connective tissue e.g are the sutures of the skull. Joints that are more loosely connected are called freely moveable or synovial joints. They are also called diarthrosis.The joints are held together by an articular capsule comprised of ligaments. A synovial membrane lines the inside of the capsule and secretes synovial fluid which lubricates the joint (hence it's name).</span>
