   2. Relevant equations
   
   
   3. The attempt at a solution
   I chose 1&2, but all three are correct. I thought for a constant pressure, if temperature is doubled, then the volume would doubled too? As P=V/T ?

   3 is not a correct statement. Change from 25°C to 50°C is not doubling the temperature. Change from 100 K to 200 K is.
