What is the definition of pressure in a fluid?
Think about how pressure behaves under different conditions.
True or False: The average distance between gaseous molecules is significantly less than their mean free path.
Consider the definitions and calculations of both terms.
If the mean free path for a given gas is 2cm, what will happen to this value if the temperature increases and why?
Consider how temperature affects speed and motion.
A container has a gaseous mixture of two types of gas, A and B. If gas A has a greater mean free path than gas B, what can you infer about their densities or molecular sizes?
Reflect on the factors that influence mean free path.
