CHAPTER WISE CLASS TEST
(Test # 5)
1. Upon heating the rate of evaporation:
2. On heating a substance, its internal energy:
3. The inter-particle attractions are the strongest in:
4. Condensation occurs when a gas is:
5. Cooling the vapours of some gases changes them directly into solid state. This phenomenon is called:
6. Condensation point is same as:
7. Physical state in which the particles possess the maximum energy:
8. During sublimation, the particles of a solid absorb energy to:
(PART – I)
i. Is condensation an endothermic process?
ii. Why do gases have no fixed shape or volume?
iii. Why does the temperature remain constant during a phase change?
iv. What happens to the particles of a solid when it is heated?
v. Is it possible to compress a liquid like a gas?
vi. Why does boiling occur at a fixed temperature?
(PART – II)
Note: Attempt the following question.
- In printing (sublimation printing): a design is printed with special solid dye on transfer paper. When heated under pressure, the dye changes directly into vapour, enters the fibres or coating of the material (polyester fabric, mugs, tiles, etc.) and turns back into solid on cooling. Since there is no liquid stage the colours do not spread or blur, so the print is sharp, bright and permanent, and does not crack, peel or fade easily.
- In air fresheners: a solid air freshener contains a scented solid. At room temperature its particles slowly gain enough energy to change directly into vapour. The scented vapour spreads in the air by diffusion and gives a pleasant smell. The solid reduces gradually without leaving any liquid residue, so it works for a long time and does not make a mess.
