1a. Two reasons that the mass of the bag levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the

interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two main types of passive processes called diffusion and filtration. This can be split into different types such as simple diffisuion‚ facilitated diffusion‚ osmosis and filtration. The objective of these experiments is to provide information on the passage of solutes and water through semi permeable membranes and relate them back to the study of actual living membranes

activated carbon‚ an adsorbent used in water filtration influence the specific surface area and the porosity. In this study‚ coconut shell was used as the raw material and activation reagents such as Hydrochloric acid‚ Zinc Chloride and Phosphoric Acid were used. A single burn and double burn process was carried out for each method. The activated carbon obtained was compared in terms of absorption capacity‚ bulk density‚ BET specific surface area and pore volume. The best results were yielded for activated

Water from the dam is screened by removing large contaminants. E.g.: Fallen Trees. Sedimentation: Allowing floc particles to settle out to form a sludge‚ which can be removed from settling tanks periodically. Filtration: Water from the settling tanks is piped to filtration tanks to be filtered. The water at this stage should be clear. Chemical Processes: Aeration: The screened water is then sprayed into the air to increase oxygen levels so that iron salt becomes oxidised and forms
