Question 1.
What happens to an object with a density less than water?
Show hintHide hint
Think about the relationship between density and buoyancy.
Question 2.
True or False: An object sinks if its density is less than the fluid's density.
Show hintHide hint
Consider what happens with a low-density object.
3Question 3.
What determines if an object floats or sinks?
- Its mass
- Its density compared to the fluid
- Its shape
Show hintHide hint
Focus on the relationship between density and buoyancy.
4Question 4.
True or False: Objects with a higher density than water will always sink.
- True
- False
Show hintHide hint
Consider the definition of density.
Question 5.
A cylindrical piece of wood has a mass of 30 grams and a volume of 50 cm³. What will happen if it is placed in water? Calculate its density and determine if it floats or sinks.
Show hintHide hint
Calculate density first using the formula.
Question 6.
Design a scenario where an object that typically sinks can float by modifying its condition. Explain the logic behind your design.
Show hintHide hint
Consider manipulating the object's overall density.
