Question

To double the volume of a given mass of an ideal gas at 27 ℃ keeping the pressure constant, one must raise the temperature in degree centigrade to

  1. 54 to the power of o end exponent    
  2. 270 to the power of o end exponent    
  3. 327 to the power of o end exponent    
  4. 600 to the power of o end exponent    

The correct answer is: 327 to the power of o end exponent


    V proportional to T rightwards double arrow fraction numerator V subscript 1 end subscript over denominator V subscript 2 end subscript end fraction equals fraction numerator T subscript 1 end subscript over denominator T subscript 2 end subscript end fraction rightwards double arrow fraction numerator V over denominator 2 V end fraction equals fraction numerator open parentheses 273 plus 27 close parentheses over denominator T subscript 2 end subscript end fraction equals fraction numerator 300 over denominator T subscript 2 end subscript end fraction
    rightwards double arrow T subscript 2 end subscript equals 600 K equals 327 ℃
