Regarding speed of sound in a gas match the following columns. ( array |l|l| & Column I & & Column II (A) & array l Temperature of gas is made 4 times and pressure 2 times array & (p) & Speed becomes 2 2 times (B) & array l Only pressure is made 4 times without change in temperature array & (a) & Speed becomes 2 times (C) & array l Only temperature is changed to 4 times array & (r) & Speed remains unchanged (D) & arr

Options

  1. A((A q, B r, C q, D s) )
  2. B((A r, B s, C q, D p) )
  3. C((A s, B p, C q, D r) )
  4. D((A p, B q, C r, D s) )

Correct answer

A. ((A q, B r, C q, D s) )

Step-by-step solution

(v= R T M = v p ) Speed does not change with change in pressure unless temperature is changed.
