Which of the following pieces of glassware would be best to choose for the following tasks?

for each task, select either the volumetric flask, erlenmeyer flask, beaker, volumetric pipet, or graduate cylinder and explain why it would be the best choice.

a. accurately deliver 15.00 ml of solution

b. heat a reaction mixture on a hot plate

c. accurately make a diluted solution to four significant figures

d. approximately deliver 15 ml of solution

Explanation:

a ) volumetric flask

b ) beaker

c ) volumetric pipet

d ) graduate cylinder

volumetric flask is more accurate than graduate cylinder . beaker is made of hard glass so it can be used for heating purpose . volumetric pipet is accurate upto 4 significant figures .

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.
