Question 5

pantera1 [17]

Answer:

The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.

Explanation:

The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.

A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.

What is the relationship between ligaments, bones and joints?

kakasveta [241]

Ligaments connect one bone to another bone. Therefore, they allow a joint to form, because joints are where two or more bones connect.

Take your knee joint for instance (***see attached pic***). The knee joint is formed by the connection of the femur (your thigh bone), the tibia (your shin bone), and the fibula (the other long bone in your lower leg). In order for all of these bones to connect there are many ligaments in the knee joint that keep the bones connected and in place. A well known example of one of these ligaments in the knee joint is the ACL (anterior crucate ligament), which is commonly torn in sports, namely football. Most people have heard of this ligament because it receives a lot of media attention since tearing it can greatly alter or even end professional athletes' careers.
