Two solid blocks of identical size are submerged in water One block is lead and the other is aluminum Upon which is the buoyant force greater?

I would say the the lead displaces less water. Think about the sizes and densities. If you have a block of lead and a block of aluminum (weighing the same), common sense tells you, the lead block is going to be a lot smaller due to his great density. Therefore, smaller block displaces less water

Why does buoyant force act upward on an object submerged in water?
The greater the pressure against the bottom of a submerged object produces an upward buoyant force
If two identical objects are placed in different fluids the buoyant force will be greater on the object in the?
The buoyant force will be greater on the object in the denser fluid.
When the pressure of the bottom of a submerged object is less than the pressure at the top of the submerged object a buoyant force is produced?

When the pressure at the bottom of a submerged object is greater than the pressure at the top of the submerged object a buoyant force is producE?

Will a submarine sink or float when its weight is greater than the upthrust acting on it?
When the weight of any object surrounded by fluid is greater than the buoyant force on it, it sinks. (The buoyant force is just the weight of the fluid that would be in that space if the submerged object were not there.)

Why does buoyant force vary with depth of the submerged object?
The buoyant force is equal to the weight of water displaced. For a dense object, such as a coin or a bowling ball, the weight of the object is greater than the buoyant force and the object will sink if you let go of it. For a less dense object, such as an ice cube or a block of balsa wood, the buoyant force is greater than the weight and you can feel it pushing the object toward the surface, resisting your attempt to hold it submerged. If you let go, the object will rise up and float.
Why does buoyant force act upward?
The buoyant force on an object submerged in a fluid is caused by the pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure at greater depth pushes upward on the object.
Mercury insert a bigger buoyant force to a fully submerged wood?
That is true. Because buoyant force is nothing but the weight of the displaced liquid when a body gets submerged in the medium of liquid. In case of mercury the relative density of mercury is 13.6 compared to that of water. A wood when placed in water, that would float due to greater buoyant force. If it is so, then you imagine about the buoyant force in case of submerging a wood in mercury. Wood having greater volume would expel that much volume of mercury. Hence the weight of the equally displaced mercury will be immense and so the result. Usually iron nails would float on mercury.
Is the The greater the surface area of an object the greater the buoyant force.?
No.
