    The graph of temperature versus pressure is a straigh line rising to the right. It Using the value above, the equation is P = 2.5522T + 699. The temperature is directly proportional to pressure. The pressure of the gas 0C using the equation,

    P = 2.5522T + 699

    P = 2.5522 (0) + 699

    P = 699
