When temperature of an ideal gas is increased from 27°C to 227°C, its rms speed is changed from 400 m/s to v_s Then, v_s is

516 m/s

450 m/s

310 m/s

746 m/s

Solution

516 m/s

We know that the rms speed is directly proportional to square root of temperature.

$v_{rms} \propto \sqrt{T} Hence, \frac{v_{rms (1)}}{v_{rms (2)}} = \sqrt{\frac{T_{1}}{T_{2}}} \frac{400}{v_{rms (2)}} = \frac{\sqrt{27 + 273}}{\sqrt{227 + 273}} = \sqrt{\frac{300}{500}} v_{rms (2)} = \sqrt{\frac{500}{300}} \times 400 = 1.29 \times 400 = 516.39 m / s \approx 516 m / s$
