1. A 15 mL balloon contains helium gas at a pressure of 545 mm Hg. (a.) What is the newpressure when the volume expands to 22 mL at a constant temperature? (b.) What law ofgases is being applied in the problem? (c.) And state their relationship.2. The volume of air in a person's lungs is 545 mL at a pressure of 860 mmHg. Inhalationoccurs as the pressure in the lungs drop to 790 mmHg. At a constant temperature, (a.) towhat volume in liter did the lungs expand? (b.) What law of gases is being applied in theproblem? (c.) And state their relationship.3. A sample of Carbon dioxide gas occupies 6.90 L at 145 °C. (a.)Calculate the temperature atwhich the gas will occupy 3.65 L, if the pressure remains constant. (b.) What law of gases isbeing applied in the problem? (c.) And state their relationship.
