Explain how temperature affects the rate of diffusion. What effect does temperature have on rate of diffusion? What factors affect diffusion? Why does temperature difference increase the rate of heat transfer?
Why does hydrogen bonding help ice cubes float? Why is the melting of ice a physical change? Why is boiling water not a chemical reaction? Why does temperature affect the rate of diffusion? Why do gases diffuse? Why does warm air rise?
(1) Suggest and explain why the scientists kept the temperature of the leaves at 20° C while they recorded results.(⑩) Calculate the percentage increase in the rate of photosynthesis at a light intensity of1250 arbitrary units when the carbon dioxide concentration was increased from 140ppm to...
Our findings suggest that unlocking the productivity potential of advanced economies requires a focus on promoting both demand and digital diffusion, in addition to interventions that help remove traditional supply-side constraints such as red tape. To incentivize broad-based change, companies need compet...
(1) and the Gibbs adsorption isotherm results in(3)dσidlna=−RTΓi,where a is the activity (can be replaced by concentration at small concentrations), R is the gas constant, T is the temperature, and Γ is the adsorption. It is possible to get using Eq. (3) that(4)dσlvcos...
Chemical Reaction Rate At low temperatures, the intercalation of lithium ions on the graphite electrode and the lithium plating reaction proceed simultaneously. Under cold conditions, the diffusion of lithium ions in graphite is inhibited and the conductivity of the electrolyte is reduced; as a result...
increase in temperature until they disappear. At this point, they are dry. The size of the wet areas does not diminish until the 320-second mark. The two adjacent drops make contact in 12 seconds and reach their final size at 28 seconds. The combined surface area of the two separate ...
Microbial culturomics was introduced in 2012 to increase knowledge of the gut microbiota repertoire. Prior to this, environmental microbiologists mimicked the bacteria's natural environment in order to facilitate its growth (5). They developed some culture process, including diffusion chambers and ichip...
Monetary policy, on the other hand, is the domain of the U.S.Federal Reserve Boardand refers to actions taken to increase or decreaseliquiditythrough the nation's money supply. According to the Federal Reserve Board, these actions are intended to "promote maximum employment, stable prices, and...
Why does the colour leak out of beetroot? Procedure to investigate the effect of temperature Hypothesis- The higher the temperature while cooking the beetroot, the more pigments well leak out from the cell membrane, hence the absorbance would increase. ...
