Question

The r.m.s velocity of hydrogen is square root of 7 times the r.m.s. velocity of nitrogen. If T is the temperature of the gas,

  1. bold T open parentheses bold H subscript 2 close parentheses equals bold T open parentheses bold N subscript 2 close parentheses
  2. straight T open parentheses straight H subscript 2 close parentheses greater than straight T open parentheses straight N subscript 2 close parentheses
  3. bold T open parentheses bold H subscript 2 close parentheses less than bold T open parentheses bold N subscript 2 close parentheses
  4. bold T open parentheses bold H subscript 2 close parentheses equals square root of bold 7 bold T open parentheses bold N subscript 2 close parentheses

The correct answer is: bold T open parentheses bold H subscript 2 close parentheses less than bold T open parentheses bold N subscript 2 close parentheses
