Asubstance is tested and is found to have the following physical qualities:
- high electrical conductivity - malleability - high luster

the substance is most likely to be a
a. metal
b. metalloid
c. nonmetal
d. cannot be determined without more data

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.

it is the most commonly accepted one

diaria maybe go see a doctor about that
