each moleculeof a gas f degrees of freedom d ratio C_p/C_v = fr d gas is [ans :1+2/f]

equal masses  of 3liquids  ABC  have temperatures 10⁰ c, 25⁰c & 40⁰c respectively   if  A&B  r mixed  d mixture  has  a temperature of 15⁰C if B& C r mixed d mixture has  a  temperature  of 30⁰C if A&C  r mixed  d mixture will have a temperature of  

Since MC₁(15-10)=MC₂(25-15)=>C₁/C₂=2

MC₂(30-25)=MC₃(40-30)=>C₂/C₃=2

MC₁(T-10)=MC₃(40-T)=

4(T-10)=40-T 4T-40=40-T  5T=80 OR T=16⁰C.

I think if the degrees of freedom are f,then C_v=fR/2 and C_p=fR/2+R.

So,C_p/C_v=f+2/2=1+2/f.

degrees of freedom are the type of motion a molecule can exibit.They r vibration,roational etc.

Degrees of freedom are ways in which a gas molecule can store its kinetic energy, they r rotational, translational and vibrational

Maxwell's equipartition law says that all gas molecules distribute their KE equaly in all degrees of freedom,

E.g: for a monoatomic gas , f=3 coz of translational in X, Y, and Z dirns.

for diatomic, f=5 coz it will have two rotationals also,

Vibrational will be neglected at this stage,since it is considered only at high temp, but it is given by 6n-4
