Pumice is a porous volcanic rock with a density less than the density of water. Pumice is created when foamy textured lava is ejected from a volcano and rapidly cooled.

Porous lava rock is called pumice. If placed in water, it would float as it possesses a density that is less than water.

Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.

The weight of a sample of lava can be very heavy (dense), or it can be porous, such as pumice. The rock itself is heavier than water, but if there are trapped air spaces with the rock, the average density can be less than that of water (it could float).

Liquid lava would have less density than its solidified counterpart.

If the object's original density is less than water (sponge, for example) - the density will increase. If the object's original density is greater than that of water (though I cannot think of anything that fits that category that is porous enough to absorb water), the density will decrease.

Saturn has a density that is less than that of water.

The density of an object is constant, therefore, no rock can have less density in water.

-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.

A cork is less denser than water because cork is floating on water so it will have less density than water

If it floats in water, it has a density less than water. Density of water is 1.0 g/mL

If water droplets penetrate within 3 minutes or less it is considered porous, if water droplets remain on top it is considered non porous..

An object will float in water if it has LESS density than the water.

The "average" density of the object must be less than that of the water displaced.

in water yes its density is less than density of water

That the material's density is less than the density of water.

The density (mass/volume) of the oil is less than the density of water. It is the same reason that ice floats on the top of water, rather than sinking. The density of frozen water (ice) is less than the density of liquid water.

User Avatar

The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.

No, it depends on the volume of water that can dissolve the salt. If the volume of water is more then it dissolves more salt and the density will be more and if the volume of the water is less then it dissolves less salt and the density will be less.
