The pressure 15.0 meters under water is 248 kPa. What is this pressure in atm?
The thing to remember about an atmosphere is that it represents the average pressure exerted by the atmosphere at sea level.
You know that pressure is defined as force per unit of surface. When you have a force of
When you have exactly
In order to have a pressure of
#248 color(red)(cancel(color(black)("kPa"))) * "1 atm"/(101.325color(red)(cancel(color(black)("kPa")))) = color(green)(bar(ul(|color(white)(a/a)color(black)("2.45 atm")color(white)(a/a)|)))#
The answer is rounded to three sig figs.
