Charles' Law Worksheet Name Directions: Calculate the following using Charles' Law. Assume constant pressure, number of moles, and containers are able to expand/contract. If a 6.50 L balloon at 22.0 °C is put into a refrigerator at 4.0 °C, calculate new volume. A 500 L balloon is heated from 20.0-75.0 C, calculate the final volume. A sample of gas is cooled from 180 °C to 25...

You are helping to design a new hot air balloon for an upcoming regatta. Assuming that the temperature to which the air inside the balloon can be safely heated is 85 ˚C, what is the minimum volume require for the balloon if it is to lift a total weight (balloon plus passengers) for 250 kg. Take the outside air temperature to be 15 ˚C, the air pressure to be 1.00 bar, and make a reasonable assumption as to the composition...
