Test: Archimedes Principle - Question 1

What instrument is used to find the specific gravity of liquids quickly and directly without calculations, working on the principle of floatation?

Detailed Solution for Test: Archimedes Principle - Question 1
A hydrometer is used to find the specific gravity of liquids quickly and directly without the need for complex calculations. It operates based on the principle of floatation.
Test: Archimedes Principle - Question 2

What is the term for the ratio of the weight of any volume of a substance to the weight of an equal volume of water at 4°C?

Detailed Solution for Test: Archimedes Principle - Question 2
Relative density, also known as specific gravity, is the ratio of the weight of any volume of a substance to the weight of an equal volume of water at 4°C. It is sometimes referred to as specific gravity because it is a pure number without units.

Test: Archimedes Principle - Question 3

The law of floatation states that a floating body displaces what in the fluid in which it floats?

Detailed Solution for Test: Archimedes Principle - Question 3
According to the law of floatation, a floating body displaces its own weight of the fluid in which it floats.
Test: Archimedes Principle - Question 4
Which type of hydrometer has a constant weight but variable immersion?
Detailed Solution for Test: Archimedes Principle - Question 4
Common hydrometers have a constant weight but variable immersion and are commonly used to measure specific gravity.
Test: Archimedes Principle - Question 5
Why does a ship made of iron and steel float in water while an iron nail sinks in water?
Detailed Solution for Test: Archimedes Principle - Question 5
A ship floats in water because it is hollow and contains air, which reduces its overall density, making it less dense than water. An iron nail, on the other hand, sinks in water because its density is greater than that of water.
Test: Archimedes Principle - Question 6
What happens to a submarine when its ballast tanks are filled with water?
Detailed Solution for Test: Archimedes Principle - Question 6
When a submarine's ballast tanks are filled with water, the average density of the submarine becomes greater than that of water, making it more buoyant and allowing it to dive easily.
Test: Archimedes Principle - Question 7
Why does a solid chunk of iron sink in water but float in mercury?
Detailed Solution for Test: Archimedes Principle - Question 7
A solid chunk of iron sinks in water but floats in mercury because mercury is denser than water. The density of a substance determines whether it will sink or float in a particular fluid.
Test: Archimedes Principle - Question 8
Why does a balloon filled with hydrogen gas rise in the air?
Detailed Solution for Test: Archimedes Principle - Question 8
A balloon filled with hydrogen gas rises in the air because hydrogen gas is lighter than air, leading to an overall decrease in density, causing the balloon to float upward.
Test: Archimedes Principle - Question 9
What happens to the level of water when ice melts in it?
Detailed Solution for Test: Archimedes Principle - Question 9
When ice melts in water, the level of water remains unchanged. This is because ice is less dense than water, and the volume of water displaced by the submerged portion of ice is equal to the volume of water produced when the ice melts.
Test: Archimedes Principle - Question 10
Why does a submarine rise to the surface when compressed air is forced into its ballast tanks?
Detailed Solution for Test: Archimedes Principle - Question 10
When compressed air is forced into a submarine's ballast tanks, it reduces the overall buoyancy of the submarine. This allows the submarine to become less buoyant and rise to the surface of the water.
