Thermal Physics
each moleculeof a gas f degrees of freedom d ratio Cp/Cv = 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

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













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
