    This is a question from Chemistry A-level 9701. In the marking scheme it says that 1 and 2 are correct, so can anybody explain me how come 3 is incorrect?? I mean if pressure, R and n are constant doubling temperature will double the volume.

    I would help, but I've had a couple of glasses of wine and everytime I put my head on one side I fall over.

    I'm pretty sure 3 is also correct. Unless I missed something in my chemistry class. Maybe double check the ms?

    It isnt uncommon for mark schemes to make mistakes, I would double check with my teacher.

    That shouldn't make a difference, no3 is still correct. The scales on celsius and kelvin are the same

    No, 50 is double of 25 but 273 + 50 is not double of 273 + 25
