An arctic weather balloon is filled with 13.2 L of helium gas inside a prep shed. The temperature inside the shed is 13. °C. The balloon is then taken outside, where the temperature is -8. °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits. ?? EP Solution as we know that P 1 V 1 / T 1 = P 2 V 2 / T 2 from the given data pressure is constant of 1 atm So we will have V 1 /T 1 = V 2 /T 2 V 1 = 13.2 L T 1 = 13 o C or 286 K V 2 = ? T 2 = -8 o C or 265 K V 2 = V 1 / T 1 T 2 = 13.2 / 286 * 265 = 1.741* 10 -4 L .
