A 5.0 liter balloon at room temperature (25.0°C) contains hydrogen gas. If the balloon is carried outside to where the temperature is –27.0°C, what volume (in liters) will the balloon change to? Hint: what unit is NOT allowed in gas law equations? Also, as usual, don't enter the unit of your answer here. Only enter the number of the correct answer. Always use significant figure and rounding rules.
