Answer:
1 Answer. (c).(2)Correct answer is option 'C'.
Explanation:
1.Gases and liquids behave like fluids. Both gases and liquids tend to flow due to less force of attraction between their particles. Also, they require vessel to keep them.
(d) Therefore, the correct sequence of temperature will be 298 K, 311 K and 339 K. On converting 25°C, 38°C and 66°C, to kelvin scale, we get the following temperatures 25°C+ 273 = 298 K 38°C + 273 = 311 K 66°C + 273 = 339 K Therefore, the correct sequence of temperature will be 298 K, 311 K and 339 K.
Correct option is
C
(i) gases, liquids, solids (ii) solids, liquids, gases
Decreasing order - empty space between solids, liquids, and gases: Gases, Liquids, Solids
Explanation - Space between particles is directly proportional to force of attraction between them, it is minimum in gaseous state and maximum in solid state because of this reason, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.
Increasing order - tendency to flow for solids, liquids and gases: Solids, Liquids, Gases
Explanation - tendency to flow is minimum in solid due to the immovably fixed position of their particles and maximum in gas particles because of least force of attraction among them.
