2. Mercury is used as the pressure measuring liquid in the barometer.
3. At sea level, the atmospheric pressure is 76 cm of mercury in the barometer.
4. In the observation of measuring atmospheric pressure, it is found that:

a) The vertical height of mercury in the tube is independent of the shape or size of the tube.

b) It does not change if the tube is tilted.

Thus, the given statement is true.
