Which represents the largest pressure?
A)five mmHg
B)one atmosphere
C)one millimeter of mercury
D)one hundred pascals
E)five pounds per square inch
I tried converting them all to mmHg and I think the answer is B, but I just want to make sure.
B is it.
To determine which option represents the largest pressure, we need to compare the given values.
First, let's convert all the units to a common measurement: millimeters of mercury (mmHg):
A) 5 mmHg (already in mmHg)
B) 1 atmosphere (atm) ≈ 760 mmHg (standard conversion value)
C) 1 millimeter of mercury (mmHg)
D) 100 pascals (Pa) ≈ 0.75 mmHg (standard conversion value - Pa is a smaller unit than mmHg)
E) 5 pounds per square inch (psi) ≈ 344.7 mmHg (standard conversion value)
Comparing the converted values, we find that:
A) 5 mmHg
B) 760 mmHg
C) 1 mmHg
D) 0.75 mmHg
E) 344.7 mmHg
From this comparison, we can see that the option with the largest value is 760 mmHg (B). Therefore, the correct answer is B) one atmosphere.
So, you were correct in your initial assessment. Well done!
To determine the largest pressure, let's compare the given options by converting them to a common unit, such as mmHg (millimeters of mercury).
Here are the conversions:
A) 5 mmHg
B) 1 atmosphere = 760 mmHg (standard value)
C) 1 millimeter of mercury = 1 mmHg
D) 100 pascals = 0.750062 mmHg (approximately)
E) 5 pounds per square inch (psi) = 342.063 mmHg (approximately)
Comparing these values, we can see that option B, which is equal to 760 mmHg (atmosphere), represents the largest pressure. Therefore, your initial assumption is correct, and the answer is B) one atmosphere.
