Question

The molecules of a given mass of gas have a root mean square velocity of 200 ms^-1 at 27°C and 1.0 × 10⁵ N m^-2 pressure. When the temperature is 127°C and the pressure 0.5 × 10⁵ N m^-2, the root mean square velocity in ms^-1 is

• A. \(\frac{400}{\sqrt3}\)
• B. \(100\sqrt2\)
• C. \(\frac{100\sqrt2}{\sqrt3}\)
• D. \(\frac{100}{3}\)

Answer 1

The Correct Option is A

The correct option is (A): \(\frac{400}{\sqrt3}\)
