The given pressure of 543 kPa is equivalent to:<\/p>\n\n\n\n
- \n
- 5.36 atm<\/strong> (atmospheres)<\/li>\n\n\n\n
- 4072.83 mmHg<\/strong> (millimeters of mercury)<\/li>\n<\/ul>\n\n\n\n
Explanation:<\/h3>\n\n\n\n
Pressure is a measure of force exerted per unit area. In this case, we are given the pressure 45.0 m underwater as 543 kPa, and we need to convert it into different units.<\/p>\n\n\n\n
Conversion to Atmospheres (atm):<\/strong><\/h4>\n\n\n\n
The atmospheric pressure at sea level is defined as 1 atm = 101.325 kPa<\/strong>. To convert from kPa to atm:<\/p>\n\n\n\n
[
P_{\\text{atm}} = \\frac{P_{\\text{kPa}}}{101.325}
]<\/p>\n\n\n\n[
P_{\\text{atm}} = \\frac{543}{101.325} = 5.36 \\, \\text{atm}
]<\/p>\n\n\n\nThis means the pressure at 45 meters underwater is about 5.36 times the atmospheric pressure at sea level<\/strong>.<\/p>\n\n\n\n
Conversion to Millimeters of Mercury (mmHg):<\/strong><\/h4>\n\n\n\n
The unit mmHg is often used in medical and meteorological applications. The conversion factor is 1 atm = 760 mmHg<\/strong>, and since 1 atm = 101.325 kPa, we use:<\/p>\n\n\n\n
[
P_{\\text{mmHg}} = P_{\\text{kPa}} \\times \\frac{760}{101.325}
]<\/p>\n\n\n\n[
P_{\\text{mmHg}} = 543 \\times \\frac{760}{101.325} = 4072.83 \\, \\text{mmHg}
]<\/p>\n\n\n\nThus, a pressure of 543 kPa<\/strong> corresponds to 4072.83 mmHg<\/strong>.<\/p>\n\n\n\n
This calculation is crucial in engineering, diving, and atmospheric studies, where understanding pressure variations is necessary for safety and operational efficiency.<\/p>\n\n\n\n
