Final answer:
To determine if an object sinks or floats, you can use its specific gravity. If the specific gravity is less than one, it will float. If the specific gravity is greater than one, it will sink.
Step-by-step explanation:
To determine if an object sinks or floats, you can use its specific gravity. Specific gravity is the ratio of the object's density to the density of water. If an object has a specific gravity less than one, it will float. If the specific gravity is greater than one, it will sink. For example, if we have an object with a specific gravity of 0.8, it will float because its density is less than that of water. On the other hand, if the specific gravity is 1.2, the object will sink because its density is greater than that of water. Therefore, by knowing the specific gravity of an object, you can determine whether it will sink or float.
