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 can't polar molecules cross by simple diffusion?
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?
(i) Suggest and explain why the scientists kept the temperature of the leaves at 20 C while they recorded results.[2](ii) Calculate the percentage increase in the rate of photosynthesis at a light intensity of1250 arbitrary units when the carbon dioxide concentration was increased from 140 ppm...
(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...
On digital, action is needed both to overcome adoption barriers of large incumbent business and to broaden the adoption of digital tools by all companies and citizens. Actions that can promote digital diffusion include: leading by example and digitizing the public sector, leveraging public procurement...
(2014) attributed Donnan effect for the increase of pH and alkalinity in the permeate and thus adding acidity to the brine during the reverse osmosis process. Higher rate of diffusion of sodium cations through the membrane compared to chloride anions, inducing a small potential difference which ...
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 ...
Monitoring the temperature of the concrete during phase III and IV is a quality control component that is regularly performed. The main reason behind this measurement is to ensure the concrete does not reach temperatures that are too high or too low. This allows proper strength development and im...
Why does temperature difference increase the rate of heat transfer? Why does greater tension increase wave speed? Why are there so many alveoli in the lungs? How do convection currents lead to atmospheric circulation? Why do liquids flow?
Why does temperature increase when water condenses? Why does wind increase transpiration rate? Why does hot air rise? How does carbon cause ocean acidification? Why does the pressure inside a container of gas increase if more gas is added to the container?
