At which temperature nitrogen under 1.00 atm pressure has the same root mean square speed as that of CO ₂ at STP

Options

  1. A0^ C
  2. B27^ C
  3. C-99^ C
  4. D-200^ C

Correct answer

C. -99^ C

Step-by-step solution

Let RMS speed of nitrogen at T ~K be u and is equal to that of CO ₂ at STP aligned u & = 3 R T 28 = 3 R 273 44 T & = 273 28 44 =173.73 ~K =-99.27^ C aligned
