Which best explains why a scientist would share these details in a conference

It informs the audience if the study included controlled tests.

Explanation: Usually, scientific conferences involve presentation of papers by scientists. These paper presentations are actually the sharing of details of the scientific research carried out by other scientists.

Presenting the materials and methods section of the a research project  to a scientific conference informs the audience if the study included controlled tests.

The inclusion of controlled tests in a scientific study enhances the validity of the results obtained in the study.

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.
