Explain in words how Charles’s law follows f)9ppz c62jk inryd4of,fh++pgd;vr -k-op+ l iom kinetic theory and the relation between avehd,+ kfo p4yp+ d-fiov-r;lg+rage kinetic energy and the absolute temperature.
参考答案:
Charles’s law states that the volume of a fixed
mass of gas increases proportionately to the absolute temperature, when the
pressure is held constant. As the
temperature increases, the molecules have more kinetic energy, and the average
force exerted by a gas molecule colliding with the boundaries of the container
is proportional to the kinetic energy.
Thus the force exerted during the collisions increases. The pressure is the force per unit area, and
so for the pressure to remain constant, the surface area of the boundaries must
increase, which means the volume of the container must increase.
