    hey i have this simple thermal physics question, and i can answer it using physical arguments, but i can't find an equation that supports these arguments.

    i tried using the equation
    

\frac{p_1v_1}{t_1} = \frac{p_2v_2}{t_2}

    but to no avail

    i figure i must be doing something pretty stupid, i just can' t work out what it is at the moment! :P

    Cheers

    1) V1 = V2

    so p1/t1 = p2/t2
    t2 = p2t1/p1

    p2 = 2p1
    t2 = 2 t1

    2) similar.
