At one atmosphere of pressure and 25°c, a hot air balloon has a volume of 4,000 liters. while still tied to the ground, the air in the balloon is heated to 68°c. when the balloon is untied, ready to float away, it has a new volume of

a) 1088 liters
b) 3496 liters
c) 4577 liters
d) 9280 liters

When measuring volume, why is it important to use the correct tools and units to attain the greatest accuracy? use specific examples from the lab to support your answer. (5 points)
