We know that the density of Al is greater than the density of water, yet why can an aluminum boat can float?

When an object is floating, it means that it is being supported by the buoyant force of a fluid (such as water or air) that it is submerged in. This buoyant force is caused by the displacement of the fluid by the object. If the weight of the object is equal to or less than the buoyant force, it will float.
Whether an object floats or sinks depends on its density compared to the density of the fluid it is submerged in. If the object is less dense than the fluid, it will float because the buoyant force is greater than its weight. If the object is more dense than the fluid, it will sink because the buoyant force is less than its weight.
Yes, an object can float in any type of fluid as long as its density is lower than the density of the fluid. For example, a helium balloon can float in air because it is less dense than air, and a boat can float in water because it is less dense than water.
Several factors can affect an object's ability to float, including its density, shape, and size. Objects with a larger surface area relative to their weight tend to float better because they displace more fluid. Temperature and pressure can also affect the density of a fluid, which can impact an object's ability to float.
Yes, the buoyant force can change over time if there are changes in the density of the fluid or the object. For example, as ice melts and turns into liquid water, its density decreases and the buoyant force on it will change. Additionally, if an object is compressed or expands, its density can change, affecting the buoyant force on it.
