The figure which represents the new volume of a balloon filled at a pressure of
Concept Introduction:
Different laws have been put forward to introduce properties of gases:
Boyle’s law:
At fixed temperature, the volume of a fixed amount of gas is inversely proportional to the pressure exerted by the gas.
Charles law: States that volume is directly proportional to temperature when the gas is held
at constant pressure and number of molecules.

- A 50-year-old man came to the emergency department after returning from foreign travel. His symptoms included persistent diarrhea (over the past 3 days) and rapid respiration (tachypnea). Blood gases were drawn with the following results: pH 7.21 pco2 19 mm Hg po2 96 mm Hg HCO3 − 7 mmol/L SO2 96% (calculated) (reference range, >95%) Why is the HCO3 − level so low? Why does the patient have rapid respiration?arrow_forwardWhat is the expiratory reserve volume in milliliters the following spirometry data?arrow_forwardCalculate the approximate PaO2 given the following conditions (assuming RQ=1): FiO2=.50 PB= 747 mmHg PaCO2= 45 mmHGarrow_forward
- A mouse is placed in a sealed chamber with air at 754.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.00 L, the temperature is held constant at 295 K. After two hours the pressure inside the bottle falls to 717.4 torr.
