Gases are fluids True False The case with which a fluid pour
Gases are fluids. True False The case with which a fluid pours is an indication of its viscosity. True False The pressure in a certain tank is -55.8 Pa(abs). True False As long as you stay on the surface of Earth, the atmospheric pressure will be 14.7 psia. True False Pressure is defined as the amount of force exerted on a unit of a substance or on a surface. Volume. Area. Weight. Mass. Which would have the greatest dynamic viscosity ?. Cold lubricating oil Lubricating oil in room temperature Fresh water in room temperature Hot water
Solution
1.Ans:a (True)
2.Ans:a (True)
3.Ans:b (False)(no negative values on absolute pressure scale)
4.Ans:a (True)
5.Ans:b (Area)
6.Ans:a (cold lubricating oil) (viscosity decreases with increaasing temperature. oils have more viscosity than water)
