3. If a balloon had a volume of 6.3 liters at a temperature of 24.0°C, and it sits in the Florida sun until it reaches a temperature of 102°F, what is the final volume of the balloon?

4. An oxygen tank contains 6.2 liters at 30.1 psi. A diver takes the tank to 60.2 psi. What is the final volume of the oxygen tank?

To find the final volume of the balloon, we can use Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature. We can express this relationship using the formula V1/T1 = V2/T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature. Using the given values, we can solve for V2:

V2 = (V1 * T2) / T1 = (6.3 * 102) / 24 = 26.25 liters

To find the final volume of the oxygen tank, we can use Boyle's Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. We can express this relationship using the formula P1 * V1 = P2 * V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume. Using the given values, we can solve for V2:

V2 = (P1 * V1) / P2 = (30.1 * 6.2) / 60.2 = 3.094 liters
