Physics · Kinetic Theory of Gases
Two ideal polyatomic gases at absolute temperatures T1 and T2 are mixed such that there is no loss of energy. If F1 and F2 represent their degrees of freedom, and n1 and n2 represent their number of moles respectively, the equilibrium temperature of the mixture is given by:
- 1n1 F1 T1 + n2 F2 T2n1 + n2
- 2n1 F1 T1 + n2 F2 T2F1 + F2
- 3n1 F1 T1 + n2 F2 T2n1 F1 + n2 F2✓
- 4n1 T1 + n2 T2n1 + n2
Correct answer
n1 F1 T1 + n2 F2 T2n1 F1 + n2 F2
