Define Fusion, Vaporization and Condensation
Fusion To transform a substance from solid to liquid by applying heat is called fusion. The definite temperature at which a solid starts to melt…

What is the Effect of Heat on Change of State?
Matter can exist in three states e.g. solid, liquid and gas. All of us know that water has three states-ice, water and vapor. These three…
Relation between Real Expansion and Apparent Expansion
If the liquid is heated directly without using any container then the expansion that you observe is termed as a real expansion of the liquid.…
Differentiate Real and Apparent Expansion of Liquids
Liquid always has to be heated keeping it in a container. The liquid, as well as the container, expand when the heat is applied. A…
Explain Expansion of Liquids
Liquids have no definite length or area. But it has definite volume. If the temperature is increased its volume increases. So, the expansion of liquid…
Explain Volume Expansion and Coefficient of Volume Expansion
The volume of a solid substance increases if its temperature is increased. It is called volume expansion. Thermal expansion is the tendency of matter to…
Explain Superficial Expansion and Coefficient of Superficial Expansion
The area of a solid is increased with an increase of temperature. It is called superficial expansion. Whenever there is an increase in the size…
Mathematical Example: Linear Expansion
Question: The length of a steel rod is 100 m at 20°C. If its length becomes 100.033 m at 50°C then determine the coefficient of…
What is Expansion of Solids?
With the application of heat the length, area and volume of solid substance expands. Linear expansion of solid and coefficient of linear expansion: When heat…
What is Thermal Expansion of Substance?
Almost all the substances expand due to application of heat and contract for the extraction of heat. When a body is heated the heat energy…
