Question

Why some logs are float and some are sink in water

Answer 1

If an object weighs less than an equal volume of water, it floats because the water can support its weight. ... An object that is more dense than water will sink. The logs that float are less dense than the logs that sink. Testing out a few samples of wood illustrates this.
