AI Thread Summary
The discussion revolves around the relationship between \( k_b \) (Boltzmann constant) and \( C_v \) (specific heat at constant volume) in the context of a homework problem involving enthalpy. The user has derived an expression for enthalpy but is unsure how to simplify it further. They suggest using the ideal gas law to eliminate pressure-volume terms. The core question remains whether there is a direct relationship between \( k_b \) and \( C_v \). The conversation highlights the need for clarity in simplifying thermodynamic equations.

Homework Statement



i solved for H=N1Cv1(Tf-T1)+V1(Pf-P1)+N2Cv2(Tf-T2)+V2(Pf-P2)

my TA says that i have to simplify this, i don't really see a good way to go about it

Homework Equations



Pf=(Tf/T1)P1 Pf=(Tf/T2)P2

The Attempt at a Solution

 
Physics news on Phys.org
I think you could use the ideal gas law to get rid of the pV terms.
 
so since PV=NkbT

H=N1Cv1(Tf-T1)+N1kb(Tf-T1)+N2Cv2(Tf-T2)+N2kb(Tf-T2)

is there a relationship between kb and Cv?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
