If a whale goes to a depth of 2000m, how many atm of pressure will it have to bear?
Think it through first, then pick an option.
- a 2
- b 20
- c 200
- d 2,000
Answer and explanation
Correct answer: c 200
Pressure rises by 1 atm per 10 m of depth, so 2000 ÷ 10 = 200 atm.
Why the other options are wrong
- a 2: A value of 2 would need 1 atm per 1000 m; the book's rate is 1 atm per 10 m.
- b 20: A value of 20 would need 1 atm per 100 m; 2000 ÷ 10 = 200.
- d 2,000: The number 2000 is the depth itself; to get the pressure it must be divided by 10.
