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 ?
Sorry I typed wrongly, I chose 1,2&3, but ans. is 1&2.3 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.
