Question

The kinetic energy of one mole gas at 300 K temperature, is E. At 400 K temperature kinetic energy is E¢. The value of E¢/E is –

• A. 1.33
• B. $\sqrt{\left( \frac{4}{3} \right)}$
• C. $\frac{16}{9}$
• D. 2

Answer 1

Answer: (A)

1.33

Answer 2

E = $\frac{3}{2}$ RT ̃ $\frac{E'}{E} = \frac{T'}{T}$=$\frac{400}{300}$=$\frac{4}{3}$ = 1.33
