An arctic weather balloon is filled with 17.9 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 4. °C. Calculate the new volume of the balloon.
You may assume the pressure on the balloon stays constant at exactly
atm. Be sure your answer has the correct number of significant digits.
