What do you mean by the word 'barometer?'

Name the two types of instruments used to measure atmospheric pressure.

Label the part 'A'

Which type of barometer is this?

The diagram shows a simple mercury barometer. If atmospheric pressure increases, what happens to level X and to level Y?

The diagram shows a set up of apparatus for measuring atmospheric pressure. If the density of mercury is

13,600 kgm^-3, determine the atmospheric pressure as measured by the instrument.

A barometer is used to determine the pressure of the atmosphere. The barometer shows the pressure on a particular day. If the density of mercury is 13,600 kg m^-3, what is the reading of the barometer?

The diagrams show a simple mercury barometer.

Which diagram shows the distance to be measured to find atmospheric pressure?

The barometer in the diagram shows the measurement of the atmospheric pressure. At sea level, the atmospheric pressure is 76 cm of Hg. Why is the reading of this barometer different?
