A solid is completely submerged in a particular liquid and floats at a constant level.when the temperature of the liquid in the solid is raised, the liquid expands more than the solid. will this make the solid rise upward remain floating or sink explained
the density will be less for the liquid, so more will be displaced to float the solid. However, the liquid rises as it expands, lifting the solid. So the solid goes down, and the liquid goes up.
Now if the density of the liquid becomes less than the solid's density, the solid sinks in the rising liquid.
When a solid is completely submerged in a liquid and floats, it means that the buoyant force acting on the solid is equal to the weight of the solid. This balance between the buoyant force and the weight of the solid dictates whether the solid will float, sink, or remain at the same level.
Now, let's consider the scenario where the temperature of the liquid in the solid is raised, causing the liquid to expand more than the solid. Since the solid is completely submerged, the expansion of the liquid will lead to an increase in its volume. This increase in volume will result in a corresponding increase in the buoyant force acting on the solid.
If the buoyant force becomes greater than the weight of the solid as a result of the expansion, the solid will experience a net upward force and will rise upward while still floating. This is because the buoyant force is responsible for pushing the solid upwards.
On the other hand, if the expansion of the liquid doesn't cause the buoyant force to exceed the weight of the solid, the solid will remain at the same level. In this case, the increase in the volume of the liquid will be compensated by an increase in its density, which may happen when substances expand upon heating.
If the expansion of the liquid is not large enough to compensate for the increase in the solid's weight due to the temperature change, the buoyant force will become insufficient to support the solid's weight. As a result, the solid will sink instead of remaining afloat.
In summary, whether the solid rises upward, remains floating, or sinks when the temperature of the liquid in the solid is raised, depends on the balance between the expansion of the liquid and its effect on the buoyant force, and the weight of the solid.
