The process by which a solid turns into a liquid is called melting. What is the difference between a liquid and a gas? Liquids have a fixed volume but take the shape of their container, while gases have neither a fixed shape nor a fixed volume. What is the process by which a liquid ...
Solid, one of the three basic states of matter, the others being liquid and gas. A solid forms from liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered, three-dimensional structure. All solids are able to resis
Is Slime A Liquid Or A Solid? Slime involves chemistry! Chemistry is all about states of matter, including liquids, solids, and gases. It is all about how different materials are put together and made up of atoms and molecules. Additionally, chemistry is how these materials act under differen...
Pipelines carry liquids, gases, or solid/liquid mixtures over great distances. They can be laid on land or under water. In comparison with other carriers, they offer an economical way to transport crude oil and natural gas, especially when the volume is large. But the cost of construction ...
Solid and/or liquid particles are sepd. from a gas stream by dividing the stream and passing the divided streams through a granular silicate which is stable at >300 degrees C. Used for removal of aerosols, dust, tar, smoke from gases. Different components at different temps. (esp. very hi...
