    2430 cubic feet of gas is gathered in standard conditions and put into 11 cubic foot tank. After the temperature of the tank is 530K. What is the preasure inside the tank? assume STP to be 273 and 2 atmosphere

    Welcome to TSR Physics.

    Could you tell us what help you need?

    This question is done using the standard formula

    \frac{p_1 V_1}{T_1}=\frac{p_2 V_2}{T_2}

    Do you know this formula?

    Just put in the values given in the question.

    To add to Stonebridge's post above, the formula is derived by simply making a ratio using this equation:

    pV = nRT

    If you made two equations of state, for both systems:

    p_1V_1 = n_1RT_1

    p_2V_2 = n_2RT_2

    The moles in either case is constant, R of course is the same in both, thus simply making a ratio:

    \dfrac{p_1V_1}{p_2V_2} = \dfrac{T_1}{T_2}

    Re-arrange to achieve the above.

    What don't you get exactly? If you want us to just give you the answer, I wouldn't suggest asking here.

    V_1 = 2430\, ft^3

    T_1 = 273K

    p_1 = 2\, atm

    V_2 = 10\, ft^3

    T_2 = 530K

    p_2 =\, ?
