A solution was prepared by dissolving 2.6061g of sodium carbonate in distilled water and making it up to 250cm3. A 25cm3 portion of the solution was titrated against hydrochloric acid. The equivalence point was reached when 18.7cm3 of the acid was added. Calculate the concentration of the hydrochloric acid in mol dm-3 and g dm-3.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
