if someone could do out 5 of these questions, that would be great. thanks 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...
