Ideal Gases

Question 1

If temperature and masses of gases are given, what does ke depend on and why?

Answer 1

Only on TEMPERATURE, the fact that they have different masses, means their mean sqaure speeds will be different, not ke

Think about it every particle in world has diff mass but can have same ke , dependent on TEMPERATURE nothing else

Question 2

Be careful for fsctor questions where they say , 1/3 has left

Answer 2

If a 1/3 has left look at the FACTOR CHANGE, itsgone from 1 to 2/3, so multiplied by 2/3!

don’t LACK

Question 3

When there is a mixture of gases, how to find factor change when they become a new volume?

Answer 3

Find the MOLES before, add them up, then make a new equation dividing by total v

Question 4

When looking at graph questions what should you always do

Answer 4

Write equation and establish what grsdient means

Then look at cinditons, okay if this changed and it means grsdient , so will grsdient
