Why is matter necessary for biological systems? Matter is what everything is made up, including biological systems. Matter can neither be created nor destroyed, only transformed.
Physical Science Thank you for your input. In this experiment, we will first be looking at how diffusion occurs in hot and cold homogenous mixtures. A homogenous mixture is one that is made up of materials that are evenly distributed throughout the mixture.
Using food coloring as our solute, or material to be dissolved, we will watch and observe the rate of diffusion occurring in both hot and cold water solvent.
Then, we can explore how the shape of a container affects the movement of particles. Problem How is diffusion affected by hot and cold temperature, and why does the shape of the container make a difference?
Materials 2 clear glass cups of the exact same size and shape 2 differently shaped clear containers narrow and widepreferably about the same size Procedure: Temperature Difference Fill one glass cup with hot water. Fill the second glass cup with cold water.
Drop drops of red food coloring in the hot cup, and drops of blue food coloring in the cold in the cold one. Watch and wait for color to disperse entirely. Differently Shaped Containers Fill both containers with the same temperature of water.
Drop one drop of food coloring in each of container and compare their rate of diffusion. Conclusions Temperature and the shape of the containers affected the rate of diffusion in both experiments.
Particles move faster in warmer water, so the red coloring spread more quickly through the cup. In addition, your access to Education.

Related learning resources Science project Electrolysis of Water Experiment In this free science fair project idea, kids will conduct an easy electrolysis of water experiment to test solutions of salt, baking soda, tap water, and more.Aside from the pumps and related plumbing, the most expensive piece of equipment is the canister containing the reverse osmosis membrane.
The more fresh water you want for a given pressure and given salinity the larger and more expensive the RO canister. Mar 29, · Best Answer: 1) Temperature because a faster temp means a faster rate of reaction 2) Concentration (water potential level) in osmosis molecules have to move from an area on high water potential to an area of low water schwenkreis.com the area of low water potential will contain more sugar molecules than Status: Resolved.
surface area are related to the rate of ion and molecule flow across a cell membrane. They apply what they have learned to a blood cell traveling through different concentrations of oxygen.
An increase in H+ content in the water reduces the levels of free solutes in the solution. Hence reducing the concentration gradient, similarly with a very basic solution there are alot of solutes in the solution, also reducing the concentration gradient. Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Essay Sample.
Aim and Background. This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to . To investigate the effect of surface area on osmosis in potato tissue Hypothesis: The larger the surface area of the potato, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger.4/5.
