In order to concentrate a solution, either more solute particles must be added or some solvent must be removed. If the solvent is nonvolatile, a solution may be concentrated by evaporating or boiling off solvent. Dilutionsare made by adding solvent to a more concentrated solution. It's common...
What is the boiling point of glass?Phase Changes:Matter can undergo several phase changes. When matter transforms from a solid to a liquid, that is called melting. The temperature where melting begins is called the melting point. When matter transitions from a liquid to a gas, the transition...
many substances, such as wood, burn in air and burn even more vigourously in pure oxygen). Mixtures do not have fixed precise melting and boiling points (which elements and compounds do have), but instead mixtures melt / freeze and boil / condense over a range of temperatures according to...
Even though the components of a mixture are unchanged, a mixture may have different physical properties than either of its components. For example, if you combine alcohol and water, the mixture has a different melting point and boiling point than either component. Examples of Mixtures Sand and w...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...

A Closed System is one in which the boundary is permeable to energy but does not permit the exchange of matter. To grab the underlying concept of the closed system definition, consider boiling water in a container with a cover on top, as shown in Figure 2. Figure 2. Water boiling in a...
Evoporation is a slow process and it occurs spontaneously at all temperature. Boiling is a fast proess and a liquid boils only at the temperature when its vapour pressure is equal to the applied external pressure.
