Question

Q1 = Write characteristics particles of Matter.
Q2 = Define latent heat of fusion , vaporisation.
Q3 = Write short note on sublimation with example.
Q4 = Differentiate between evaporation .​

Answer 1

Answer:

1. particles move continuously , particles are very small in size, particles have intercellular space between them.

2. The heat of fusion is the quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change . It is also a latent heat and is sometimes called the latent heat of fusion.

Vaporization means water convert into vapours in a normal atmospheric temperature this is purely natural process.

3. Sublimation is a chemical process where a solid turns into a gas without going through a liquid stage. ... An example of sublimiation is when ice cubes shrink in the freezer.

4. Vaporization is the natural process in this process water convert into vapour at a normal atmospheric temperature it is purely natural process while evaporation is not a natural process . in the process of evaporation water convert into vapour at hundred degree Celsius . this is a basic difference between the vaporization and evaporation.
