Why do gases have two specific heat capacities?
Answer (1)
Gases absorb heat differently depending on conditions:
Cₚ (at constant pressure) when the gas expands.
Cᵥ (at constant volume) when it stays in the same space.
The extra energy in Cₚ goes into expansion!
What is the mean free path?
It’s how far a gas molecule travels before colliding with another. Like walking in a crowd, some go farther before bumping into someone!
