How does suspension filtration work?
Suspension filtration works by passing a mixture of solid particles and liquid through a filter medium. The solid particles are too large to pass through the filter, so they are retained on the surface or within the pores of the filter. The liquid, which is now free of the solid particles, passes through the filter and is collected on the other side. This process separates the solid particles from the liquid, allowing for the purification or concentration of the liquid.

What is the difference between filtration and diffusion?
Filtration is a process where a barrier with small pores is used to separate particles based on size, allowing smaller particles to pass through while larger particles are retained. Diffusion, on the other hand, is the movement of particles from an area of higher concentration to an area of lower concentration, resulting in a uniform distribution of particles. In filtration, the separation is based on size, while diffusion is based on the concentration gradient of the particles.

What are the consequences if outward filtration predominates?
If outward filtration predominates, it can lead to dehydration and a decrease in blood volume. This can result in decreased blood pressure and reduced blood flow to vital organs, leading to potential organ damage. Additionally, the loss of important proteins and electrolytes through excessive outward filtration can disrupt the body's balance and lead to further complications such as electrolyte imbalances and impaired organ function. Overall, outward filtration predominance can have serious consequences for the body's overall health and function.

What is the filtration capacity of the Malawi tank?
The filtration capacity of the Malawi tank depends on the specific filtration system being used. However, for a typical Malawi tank setup, it is recommended to have a filtration system that can handle at least 10 times the volume of the tank per hour. For example, if the Malawi tank has a volume of 100 gallons, the filtration system should be able to process at least 1000 gallons of water per hour. This is necessary to maintain the water quality and clarity in the tank, as Malawi cichlids are known to produce a significant amount of waste.

Which material properties are used in filtration and evaporation?
In filtration, material properties such as pore size, porosity, and surface area are important factors. Pore size determines what size particles can pass through the filter, while porosity affects the flow rate of the filtration process. Surface area is crucial for maximizing contact between the material and the substance being filtered. In evaporation, properties such as thermal conductivity, heat capacity, and surface tension are utilized. Thermal conductivity helps in the efficient transfer of heat to evaporate the liquid, while heat capacity determines how much energy is needed for evaporation. Surface tension plays a role in the rate of evaporation by affecting the ease with which molecules can escape the liquid phase.

With which everyday objects can diffusion, osmosis, and filtration be demonstrated?
Diffusion can be demonstrated with everyday objects such as a drop of food coloring spreading in a glass of water. Osmosis can be demonstrated using a potato placed in a solution of salt water, where water will move from the potato into the salt solution. Filtration can be demonstrated using a coffee filter to separate coffee grounds from brewed coffee. These processes can be easily observed and understood using common household items.

How does the filtration system work in the Fluval Fresh F90?
The Fluval Fresh F90 features a 3-stage filtration system that ensures optimal water quality for your aquarium. The first stage is mechanical filtration, where a foam pad traps debris and particles from the water. The second stage is chemical filtration, using activated carbon to remove impurities, odors, and discoloration. The final stage is biological filtration, where beneficial bacteria colonize on the biomax media to break down harmful ammonia and nitrite into less harmful nitrates. This comprehensive filtration system helps maintain a healthy and balanced aquatic environment for your fish and plants.

What are the separating properties of evaporation, decantation, filtration, and sedimentation?
Evaporation separates a soluble solid from a liquid by heating the mixture and allowing the liquid to evaporate, leaving the solid behind. Decantation separates a liquid from a solid by carefully pouring off the liquid, leaving the solid behind. Filtration separates a solid from a liquid by passing the mixture through a filter, which traps the solid particles while allowing the liquid to pass through. Sedimentation separates solid particles from a liquid by allowing the mixture to sit undisturbed, causing the heavier particles to settle to the bottom of the container.

Which mixture is separated during the filtration of coffee and tea?
During the filtration of coffee and tea, the mixture that is separated is the liquid portion (coffee or tea) from the solid portion (ground coffee beans or tea leaves). The liquid portion passes through the filter, while the solid portion is retained, resulting in a clear liquid without the solid particles. This process helps to remove any residue or particles from the brewed coffee or tea, resulting in a smoother and cleaner beverage.

Why is the dissolved salt not found in the residue during filtration?
When a salt is dissolved in water, it forms a homogeneous solution where the salt particles are surrounded by water molecules. During filtration, the water and salt solution passes through the filter paper, leaving behind any solid impurities in the residue. The dissolved salt particles are small enough to pass through the filter paper along with the water molecules, so they are not found in the residue. This process allows for the separation of the dissolved salt from any solid impurities.

Why can saline solution not be separated into salt and water by filtration?
Saline solution cannot be separated into salt and water by filtration because the salt is dissolved in the water at a molecular level, meaning the salt particles are too small to be caught by the filter. Filtration works by trapping solid particles in a filter, but since the salt is dissolved, it passes through the filter along with the water. To separate the salt from the water in a saline solution, a process such as evaporation or distillation would be needed to remove the water and leave the salt behind.
