Archimedes principle

Question 12

It is calculated by
(body weight in the air – weight in the water)
/ density of water

Answer 12

Body volume

Question 26

You and your friend have a bet – whoever has the largest vital capacity receives a pizza from the other person. Your friend’s measured vital capacity is 4.4 L (ATPS). Measurements were made at 27 degree C and 760mmHg. Your measured vital capacity is 4.4 L (ATPS). Measurements were made at 20 degree C and 760mmHg. You are both the same height and weight. Who has the largest vital capacity (BTPS) and receives the free pizza?
Factor for conversion (1.102 at 20 degree C, 1.063 at 27 degree C)

Answer 26

You
