What is a diatomic gas?
Think of common gases like O₂ and N₂.
How many degrees of freedom do diatomic gases have?
Recall the types of movements a molecule can have.
What is the formula for the internal energy of a diatomic gas?
Recall how many degrees of freedom diatomic gases have.
Diatomic gases have how many degrees of freedom?
Consider the types of movement they have.
If a diatomic gas has a temperature increase of 100 K and contains 2 moles, calculate the change in internal energy.
Keep track of moles and convert them into molecules for calculations.
A 1 mole sample of a diatomic gas with a rotational contribution has a total energy of 15 R at a specific temperature. What is the temperature?
Use the relationship between total energy and temperature with specific heat.
