What is base? what Is the sugar also a base?

base is also known as alkaline

n sugar is not a base

The glucose acts like a base, and donates a hydroxide ion. The proton and the hydroxide ion combine to form water, and the two simple sugars combine to form sucrose. Sugar is neither an acid nor a base.

Sugar has a neutral pH which means it is neither basic or acidic just like water. However, some processed sugars may be a little acidic or basic based on how they were made.

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.
