20A ship made of iron floats because it displaces enough water to equal its weight.
Aluminum foil ball floats on water.
Submarines can control their depth by adjusting water in ballast tanks.
Fish sink when they release air from their swim bladder.
Helium balloons float because helium is denser than air.
Hot air balloons rise because hot air inside has lower density than surrounding air.
The weight of water displaced by a floating object is less than the weight of the object.
A hydrometer floats less on high-density liquids.
The law of floatation is Weight of object = Weight of liquid displaced.
Shape of an object does not affect whether it floats or sinks.
Percentage: 0%
When a ship enters a river from the sea, it sinks more than before. What is the reason?
What is the condition for a hydrogen balloon to fly upwards in the air?
A ship floats on water because:
Aluminum foil floats as a sheet but sinks as a ball because:
Submarines sink deeper in water by:
Iron sinks in water because:
The principle that governs floating objects is:
For an object to float partially in a liquid:
A hydrometer floats higher on:
Hot air balloons float because:
An object floats in a liquid when the ______ equals its weight.
The law of floatation states that Weight of object = ______ of liquid displaced.
An aluminum foil ball sinks in water because it displaces ______ water than its weight.
A sheet of aluminum floats on water because it displaces ______ water to balance its weight.
Iron sinks in water, but a ship made of iron floats because of its ______ shape.
Submarines float or sink by controlling the amount of ______ in their ballast tanks.
A fish floats upward by filling its ______ bladder with air.
Helium balloons rise in the air because the ______ on the balloon is greater than its weight.
Hot air balloons fly because the ______ of hot air inside the balloon is less than the surrounding air.
The hydrometer floats more on ______ liquids because they exert more upthrust.
