QUESTION 30 Which characteristic of water allows it to act as a potential lubricant? a.Its ability to dissolve substances O b.lts incompressibility Oc.Its heat-holding capacity Od. Its chemical reactivity e.Its ability to bond with other substances ​

Answers

Answer 1

The characteristic of water that allows it to act as a potential lubricant is its ability to bond with other substances is "Its ability to bond with other substances," is the correct answer.

The correct answer is option E.

Water is a polar molecule, meaning it has a slightly positive charge on one end (hydrogen) and a slightly negative charge on the other end (oxygen). This polarity gives water the ability to form hydrogen bonds with other polar molecules or ions.

When it comes to lubrication, water acts as a lubricant due to its ability to form a thin layer between surfaces, reducing friction. This is particularly evident in scenarios where water acts as a lubricant in biological systems, such as joints and synovial fluid.

In joints, water acts as a lubricant between the cartilage surfaces, reducing friction and allowing smooth movement. It helps to cushion and protect the joints during physical activities. Water's ability to bond with other substances allows it to create a lubricating film between two surfaces, enabling them to glide past each other with minimal resistance.

Furthermore, water's lubricating properties extend beyond biological systems. It is often used as a lubricant in various industrial applications, such as in machinery or manufacturing processes, to reduce friction and facilitate movement.

In summary, water's ability to bond with other substances, particularly its capacity to form a lubricating layer between surfaces, makes it an effective lubricant. This property is due to water's polarity and its capability to create hydrogen bonds, enabling smooth movement and reducing friction in biological systems and other applications.

The shooting that occurred in Birmingham, Alabama on the 21st is just one of the many gun-related incidents that have plagued the United States. The fact that there have been 230 mass shootings in the country since 2023 is a staggering statistic that highlights the need for more stringent gun control laws.

It is unacceptable that so many lives have been lost due to gun violence. The incident in Birmingham is a clear indication that people are not safe even when they are out having a good time. The fact that the shooting occurred outside a bar is a reminder that we cannot afford to be complacent when it comes to gun violence. While there are certainly legitimate reasons for owning a firearm, the sheer number of guns in circulation in the United States is a major contributor to the problem. It is essential that lawmakers take steps to address this issue, such as introducing universal background checks and closing loopholes that allow people to purchase guns without proper oversight. The Gun Violence Archives website serves as a stark reminder of the impact that gun violence has on communities across the country. The fact that more than 16,000 people have died in gun-related incidents since 2023 is a tragedy that cannot be ignored. It is time for action to be taken to address this issue, and for the safety and security of the American people to be made a top priority.
