Problem: An arctic weather balloon is filled with 1.87 L of helium gas inside a prep shed. The temperature inside the shed is 15.°C. The balloon is then taken outside, where the temperature is - 43.°C. Calculate the new volume (L) of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits.
