QIJ Give the reason behind the followings: 1- All gases can be considered as compressible fluids. 2- The force at a surface at rest with respect to the fluid must act normal to the surface. 3- Mercury is always used in the manometer. 4- Piczometers cannot be used to measure the vacuum (negative) pressures of liquids 5. The viscosity of all liquids decrease with increasing in temperature
