Question

. What is the temperature of a system that consists of 4.00 moles of argon behaving as an ideal gas with an internal energy of 15500 J?

Answer 1

Solution.

Argon has three degrees of freedom, since its molecule consists of a single atom.

$\Delta U = \frac{3}{2} n \times R \times T$

$T = \frac{\Delta U}{\frac{3}{2} \times n \times R}$

T = 310.9 K

Answer:

T = 310.9 K
