Question

1. Arrange solid, liquid and gas in the increasing order of forces of attraction between the
particles.
2. Why are you able to compress sponge?
3. Define i) Compressibility b) Rigidity c) Fluidity d) Diffusion e) Latent heat of Fusion
f) Latent heat of vaporisation
4. Demonstrate an activity to explain boiling point of water. Also draw a neat labelled
diagram and define the terms involved (Latent heat, Latent heat of vaporisation etc)
5. Convert the following temperatures in Kelvin scale to centigrade scale
Note: Centigrade temperature +273 = Kelvin temperature
i) 443K ii) 273K iii) 678K
6. Convert the following centigrade temperature to Kelvin scale
i) 25 o C ii) 38 o C ii) 100 o C
7. Name the process involved in conversion of a)Solid to Gas b) Gas to Liquid c) Solid to
liquid d) Liquid to gas

Answer 1

Answer:

solid then liquid then gas

Explanation:

solid have a greater attractive force than liquid & liquid have greater attractive force than gas

Answer 2

Answer:

1. Gas, liquid and solid (increasing)

2. We’re able to compress sponge because the space between the intermolecular particles is minimum.

5. i) centigrade temperature + 273 = 443K

centigrade temperature =443 - 273

Centigrade temperature = 170K

ii) centigrade temperature = 273-273

centigrade temperature = 0 K

iii) centigrade temperature =678-273

centigrade temperature = 405K
