Changes of State<br />
When a solid is heated, its temperature rises until it<br />
reaches its melting point.<br />
Any additional heat added to the material will not<br />
raise the temperature until all of the material is melted.<br />
When a liquid is heated, its temperature rises until it<br />
reaches its boiling point.<br />
The names of the changes in state are melting,<br />
freezing, boiling, condensation, sublimation and<br />
deposition.<br />
The temperature of a material will increase until it<br />
reaches the point where the change takes place.<br />
A material will change from one state to another at<br />
specific combinations of temperature and surrounding<br />
pressure, typically at atmospheric pressure. 4
