The air in a cylinder with a piston has a volume of 215 mL and a pressure of 625 mmHg. To obtain a higher pressure inside the cylinder at constant temperature, should the cylinder change as shown in A or B? Explain your choice in part (A). If the pressure inside the cylinder increases to 1.3 atm, what is the final volume of the cylinder? (The temperatue remains constant) Express your answer using two significant figures.

A scuba diver 40 ft below the ocean surface inhales 55.0 mL of compressed air from a scuba tank at a pressure of 3.20 atm and a temperature of 7 ∘C. What is the final pressure of the air, in atmospheres, in the lungs when the gas expands to 155.0 mL at a body temperature of 37 ∘C, and the amount of gas does not change?

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...

In a collision of sufficient force, automobile air bags respond
by electrically triggering the explosive decomposition of sodium
azide (NaN3) to its elements. A 43.398 g sample of
sodium azide was decomposed, and the nitrogen gas generated was
collected over water at 22°C. The total pressure was 798.8 mmHg.
How many liters of dry N2 were generated?

Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit. The volume is not accurate on a flask to the number of significant figures required for this experiment The volumetric markings on the flask do not extend to it's full height...
