What is meant by the statement “the atmospheric pressure at a place is 76 cm of Hg"? State its value in Pa.

Explanation

To solve the question, we will break it down into two parts: understanding the meaning of "76 cm of Hg" in terms of atmospheric pressure, and then converting that pressure into Pascals.

### Step 1: Understanding Atmospheric Pressure
The statement "the atmospheric pressure at a place is 76 cm of Hg" means that the pressure exerted by the atmosphere at that location can support a column of mercury that is 76 centimeters high. This is a standard reference for atmospheric pressure.

### Step 2: Formula for Pressure
To convert this height of mercury into pressure, we use the formula for pressure:
\[ P = \rho g h \]
