Question

what is the methodology of the answers ( how i can get the answer ) ?

onstant volume (cv) different than the heat capacity (Cp) at 6. How is the heat capacity of a gas a constant volume (cv) constant pressure? A. Cv is larger than Cp Bip allows for an increase in volume C. Cv is only different for monatomic gasses D. Cp is car more easily measured than Cv 7. Which of the following is one method for measuring the heat capac A Speed of sound thod for measuring the heat capacity ratio of a gas? B. Bomb calorimetry C. Infrared spectroscopy D. Isothermal titration calorimetry 8. In the adiabatic expansion method, argon expands against constant atm without exchange of energy. When the gas expanded what happened to the A. It increased 8. decreased C. It didn't change D. We can't tell 9. Comparing argon to helium, which has the faster speed of sound and why? A. Helium is faster because it has a larger theoretical heat capacity ratio B. Helium is faster because it has a smaller mass C. Argon is faster because it has a larger theoretical heat capacity ratio D. Argon is faster because it has a larger mass 10. As molecules get more complicated, does their heat capacity increase or decrease? Why? A. Heat capacity increases because as fewer degrees of freedom are available to store energy B. Heat capacity decreases because as fewer degrees of freedom are available to store energy (C. leat capacity increases because as more degrees of freedom are available to store energy D. Heat capacity decreases because as more degrees of freedom are available to store energy 11. As molecules get more complicated, does their heat capacity ratio increase or decrease? A. Heat capacity ratio decreases because the overall heat capacity increases B. Heat capacity ratio decreases because there are fewer degrees of freedom C. Heat capacity ratio increases because the overall heat capacity increases D. Heat capacity ratio increases because there are more degrees of freedom 12. What are examples of degrees of freedom? A. Legal, invisible, squandered B. Up, down, and charmed C. Fixed, partially free, free D. Translational, rotational, vibrational

Explanation / Answer

Ans 6 b) Cp allows for an increase in volume

C refers to specific heat. p and v stands for constant pressure and constant volume respectively. So Cp is the specific heat of the substance at constant pressure whereas Cv is the specific heat of the substance at constant volume.
