What is the pressure of 35.0 m under water in atmospheres (atm)?
The pressure of 35.0 m under water, which is 445 kPa, is equal to approximately 4.38 atmospheres (atm). It is important to understand the concept of pressure and its units of measurement.
Understanding Pressure and Conversion
Pressure is defined as the force per unit area exerted by a fluid or gas on a surface. In this case, the pressure of 35.0 m under water is given in kPa. To convert this to atm, we need to use the conversion factor of 1 atm = 101.3 kPa.
Calculation
Using the conversion factor, we can calculate the pressure in atm:
445 kPa / 101.3 kPa/atm = 4.38 atm (rounded to two decimal places).
Step-by-Step Conversion
If you want to convert the pressure of 445 kPa at 35.0 m underwater to atmospheres (atm), follow these steps:
1. Know the conversion factor between kPa and atm. 1 atm is equal to 101.325 kPa.
2. Divide the pressure in kPa (445 kPa) by the conversion factor (101.325 kPa/atm): 445 kPa / 101.325 kPa/atm = 4.38 atm.
Therefore, the pressure of 35.0 m under water is equivalent to 4.38 atm. This conversion allows for a better understanding of pressure measurements in different units.
