Why is a piece of pumice lighter than obsidian of equal size?

Pumice has an extremely low density due to its vesicular nature. Obsidian is not characteristically vesicular like pumice and its density is greater. Therefore, in equally sized samples pumice is lighter.


What is the density of pumice?

Since it floats in water it has a density less than 1.00


How does pumice float in water?

Pumice is full of air pockets which make its overall density less than that of water.


How much density does pumice have?

What is the name of the porous lava rock with a density less than water?

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.

What is the name of a porous lava rock with the density less than water?

Pumice.


What is the density of 1.3kg of pumice rock?

Pumice is not one rock - it is porous volanic mineral and can have vastly different ammounts of gas/holes in it, making its density highly variable. Many forms/types float in water.


Name an extrusive rock with a very low density?

Pumice is an extrusive igneous rock with a density less than that of water.


What stone can float on water?

Pumice stones will, these are low density rocks formed by volcanoes


Igneous rocks that are light colored and have a lower density?

Volcanic ash, pumice or rhyolite


What rock will float on water?

Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.


What is the density of a 49.8g piece of pumice that has a volume of 83cm3?

density = mass/volume 49.8/83 =0.6 g per cm3


Which type of stone is lighter than water?

Why is pumice lighter than water?

It depends what kind you have... If its density is less then the water it is floating in, yes.


How can you tell pumice and scoria apart?

Pumice and scoria have similar properties, like both being extrusive igneous rock with adjacent vesicles. Although pumice is less dense than scoria and its density is so low that it will float on water.


Why does pumice float in water using buoyancy and density?

Although pumice is volcanic stone, it has air pockets inside making it less dense than water, so it floats.


Why does pumice float in water?

Pumice is an extrusive igneous rock that has a lower density than an equal volume of water. Pumice forms from an airborne, rapidly cooled frothy magma, full of tiny gas pockets, making it extremely light in weight.


What is the name of a porous rock with the density less than water?

Pumice is porous and lighter than water.


Pumice is a volcanic rock that floats Its density is?

With out knowing further knowledge about the rock it is unable to determine the exact density. However, since the rock floats, presumably in water, the density must be less then 1.00g/L.


What type of density do rocks have?

They can have lots of different densities from 7.6 for Galena (a lead bearing mineral) to .9 for pumice (a type of volcanic rock). For comparison, water has a density of 1.


Does pumice have a cleavage?

No. Pumice is amorphous.


Is pumice magnetic?
