Question

(b) Which units are appropriate
for expressing atmospheric pressures, N, Pa, atm, kg>m2?

Accepted Answer

Hi everyone here we have a question asking which of the following our units used to express atmospheric pressure. So jules expresses energy. Atmospheres expresses pressure pounds per inches. Pressure equals force over area, and inches is not an area, so it is not C. In times in meters squared. Again, pressure equals force over area, and that is not force over area, so it cannot be D and E millimeters of mercury. That is a pressure. So our answers here are A and E. Thank you for watching. Bye.
