求问一道关于气体的化学英文题
Consider two gases,A and B,in separate 1.0 L containers at the same temperature and pressure.The total mass of gas A in the container is 0.25 g and the mass of gas B in the container is 0.51 g.
1.Which gas has the most molecules present?
2.Which gas has the largest average kinetic energy?
3.Which gas has the fastest average velocity?
4.How can the pressure in the two containers be equal to each other since the larger gas B molecules collide with the container walls more forcefully?

3.Which gas has the fastest average velocity?
4.How can the pressure in the two containers be equal to each other since the larger gas B molecules collide with the container walls more forcefully?
1.the number of molecules are equal
2.average kinetic energy are the same
3.A has faster speed
4 Because of perfect elastic collision,and also there is more collision between the wall and gas A
再问： 第四问不是问的是how吗？？你给的答案好像不太对啊
再答： 呵呵，如果高中最简单的物理我都搞错了，我大学算是白上了。如果错了，你随时可以来喷我。
再答： 英文你也要看意思理解啊，这里它用how是让你反驳它的论点，所以不用why
再答： 自己学习下“ideal gas law" 看看同温同压，单位摩尔气体体积是否一致
