What is a barometer ? How is a simple barometer constructed ?

How is the barometric height of a simple barometer affected if A drop of liquid is inserted inside the tube?

A barometer correctly reads the atmospheric pressure as 76cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then become constant. If the saturation vapour pressure at the atmospheric temperature is 0.80cm of mercury, find the height if the mercury column when it reaches its minimum value.

How is the barometric height of a simple barometer affected if Its tube is pushed down into the trough of mercury?

How is the barometric height of a simple barometer affected if Its tube is slightly tilted from vertical?
