A hot air balloon is filled with 1.51 × 106 L of an ideal gas on a cool morning (11 °C). The air is heated to 103 °C. What is the volume of the air in the balloon after it is heated? Assume that none of the gas escapes from the balloon.

  1. the volume is directly proportional to the ABSOLUTE (ºKelvin) temperature
    ... K = C + 273

    v = 1.51E6 L * [(103 + 273) / (11 + 273)]
