A. True 10 metres of waterapproximately one atmosphere.

B. True Total alveolar pressurefour atmospheres.

C. False Haemoglobin is already saturated with O2 at sea level and cannot take up more; the amount of dissolved oxygen increases raising total O2 content by less than 10 per cent.

D. False This depends on temperature alone.

E. False More energy is needed to move air made more viscous by compression.
