Answer:
101201.2 Pascal.
Step-by-step explanation:
Given that the difference h between the two liquid levels is 2.0 cm. The density of the liquid is 800 kg /m3.
Calculate the difference between the pressure of the gas and atmospheric
pressure.
The pressure of the gas can be calculated by using the formula
Pressure = density × acceleration due to gravity × height
Substitute all the parameters into the formula
Pressure = 800 × 2/100 × 9.8
Note that the height is converted to metre.
Pressure = 156.8 Pascal
pressure difference = 101358 - 156.8
Pressure difference = 101201.2 Pascal
