If a cylinder's density is 5g, and water is 1.0g, will the cylinder sink or float?

To determine whether the cylinder will sink or float, we need to compare the densities of the cylinder and water. If the density of the cylinder is greater than the density of water, the cylinder will sink. If the density of the cylinder is less than the density of water, the cylinder will float.

Given that the density of the cylinder is 5g and the density of water is 1.0g, we can see that the density of the cylinder is greater than the density of water. Therefore, the cylinder will sink.
