An irregular solid is defined as a three-dimensional solid object that does not have an normal shape, such as a sphere, cube or pyramid. Irregular solids have many sides of differing lengths. More » Science Chemistry States of Matter

A solid is scientifically defined as having structural rigidity and particles arranged with a relatively stable shape and a relatively stable volume. Unlike other states of matter, solids do not expand to take on the sha... More » Education

To measure the volume of an irregular solid, pour water in a graduated cylinder, read the water volume, immerse the object in the cylinder, and subtract the initial water volume from the new volume to get the volume of t... More » Science Measurements

Purdue University's Department of Chemistry defines "liquid" as a state of matter that flows, can change its shape, is not easily compressible and maintains a relatively fixed volume. Liquid is one of the four primary st... More » Science Chemistry States of Matter

Solids are defined as substances that retain their shape, even when they are not confined. Substances usually assume the solid state of being at lower temperatures than they do when they are liquids, gases or plasmas. More » Science Chemistry States of Matter

Hydrogen is a non-metal element that is a gas at room temperature. It is used in combination with other elements to create liquid compounds such as hydrochloric acid, ammonia and hydrogen peroxide, and it combines with t... More » Science Chemistry States of Matter

Shape can drastically alter the amount of time it takes for an ice cube to melt. Given standard atmospheric pressure, ice cubes melt when their temperature rises above 32 degrees Fahrenheit. This only happens if the ice ... More » Science Chemistry States of Matter
