Water Properties Trivia! Chemistry Practice Quiz

Sodium chloride is the scientific name for salt, specifically table salt. This compound is composed of sodium (Na) and chlorine (Cl) ions, which combine to form a crystal structure. Sodium chloride is commonly used as a seasoning and preservative in food, as well as in various industrial processes. Its scientific name reflects its chemical composition and is widely recognized as the common name for this essential mineral compound.

Remember to divide Mass(weight) by density!

As you descend into the ocean, the amount of light in the water actually decreases. This is because sunlight can only penetrate the top layer of the ocean, and as you go deeper, less and less light is able to reach those depths. The water absorbs and scatters the light, resulting in a decrease in the amount of light available.

Hope you're dealing with the pressure of the impending test!

As you descend into the ocean, the temperature of the water generally decreases rather than increases. This is because sunlight can only penetrate the top layers of the ocean, and as you go deeper, there is less sunlight and therefore less heat. Additionally, cold water from deeper parts of the ocean tends to rise to the surface, causing the overall temperature to decrease with depth.

There's more "stuff" or particles in salt water so it will be more dense!

I sure hope you didn't say anything about salinity!

the fraction line always means divide!

It must be colder which is a lower temperature so it's true!

As you descend into the ocean, the pressure increases, which in turn causes the density of the water to increase. This is because the weight of the water above exerts more pressure on the water below, compressing it and increasing its density. Therefore, it is true that as you go deeper into the ocean, the density of the water increases.

As long as we're on earth, weight is our easiest way to measure mass

As you descend into the ocean, the salinity of the water increases because the process of evaporation leaves behind the salt content, making the water more concentrated with salt. This phenomenon is also influenced by factors such as the location of the ocean and the inflow of freshwater from rivers. Therefore, it is true that the salinity of the water increases as you go deeper into the ocean.

density = mass/volume

Less fresh water = increased salinity

They may live in the water, but they are still animals so they still need oxygen. Just like land animals including you!

Cold water is denser than hot water. When water is heated, the molecules gain energy and move faster, causing them to spread out and take up more space. This increase in volume leads to a decrease in density. On the other hand, when water is cooled, the molecules slow down and come closer together, resulting in a decrease in volume and an increase in density. Therefore, cold water is denser than hot water.

Making it bigger spreads out the "stuff" inside making it less dense.

The dead sea is in the middle of a desert. That means it's a very hot environment which leads to a lot of evaporation which leaves a high level of salt behind.

Less fresh water = increased salinity

More fresh water = decreased salinity

Volume is how much space something takes up which is it's size

Remember it doesn't affect the volume of the water at all since it dissolves into the water and fits between the water molecules!

Remember to divide Mass(weight) by density!

As you descend into the ocean, the pressure increases due to the weight of the water above. The density also increases because colder water is denser than warmer water. Additionally, the amount of gases, such as oxygen and carbon dioxide, decreases as you go deeper into the ocean. This is because the concentration of dissolved gases decreases with increasing depth. Lastly, the amount of light decreases as you descend into the ocean because water absorbs and scatters light, making it difficult for sunlight to penetrate to deeper depths.

it is 35/1000 or 35 parts out of every thousand parts. That would be 3.5%(which wasn't an option)

When a diver swims to the top too quickly, the pressure decreases rapidly, causing nitrogen gas to form bubbles in their blood. This condition is known as "the Bends" or decompression sickness. Nitrogen is the most common gas present in the air and is also the gas that makes up the majority of the gas mixture used for diving. As the diver ascends, the nitrogen absorbed by their body tissues during the dive comes out of solution and forms bubbles, which can cause various symptoms like joint pain, dizziness, and even paralysis if not treated promptly.

The top of the transition zone is where all light ends. There is only light in the surface zone.
