What are the characteristics of upthrust?
Expert Answer:
- The upthrust has the following three characteristic properties :
- (i) Larger the volume of body submerged in fluid, greater is the upthrust.
- (ii) More the density of fluid, greater is the upthrust.
What is the unit of specific gravity?
It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.
Does temperature affect specific gravity?
Can temperature affect specific gravity? Yes, it can. When using water as a reference for establishing specific gravity, it is almost always assumed that the water is at 4°C, when it’s densest. Water itself becomes less dense as it becomes warmer until it evaporates and becomes steam vapor at boiling point.
What are the application of specific gravity?
Specific gravity has many other applications: gemologists use it to distinguish similar gems; chemists, to check on the progress of reactions and the concentration of solutions; and auto mechanics, to test battery fluid and antifreeze.
What is the relationship between temperature and specific gravity?
When the specific gravity is defined based on water at 4°C, then the specific gravity is equal to the density of the liquid. However, if the specific gravity is expressed at different temperatures, it will no longer be equal to the density.
What does a specific gravity of 1.030 mean?
Specific gravity. Normal: 1.005–1.030 footnote 1. Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
What is specific gravity of alcohol?
