Question

Four beakers A, B, C and D contain hot water having temperature 279 K, 30°C, 300 K and 90°C respectively. If one drop of ink was added gently to each of them then the correct order of rate of diffusion will​

Answer 1

Answer:

diffusion order is 300,200,90,30

Answer 2

Activity to show diffusion of ink in water

Explanation:

Four beakers A, B, C and D.

• Temperature of beaker A: 279 K
• Temperature of beaker B: 30°C = 273 + 30= 303 K
• Temperature of beaker C: 300 K
• Temperature of beaker D: 90°C = 273+90= 363 K

Order of temperature of water in beakers:

Beaker D > beaker B > beaker C > beaker A

One drop of ink added gently to each beaker of water.

Rate of diffusion was observed.

Observation:

Rate of diffusion of ink was highest in beaker D.

Rate of diffusion of ink was lowest in beaker A.

Order of rate of diffusion:

Beaker D > beaker B > beaker C > beaker A

Water in beaker D is at highest temperature.

Kinetic energy of water molecules in beaker depend on the temperature. Greater the temperature, higher the kinetic energy.

Higher the kinetic energy possessed by molecule, Higher the random motion of water molecules: Increased diffusion of ink.

Rate of Diffusion of ink in water is directly proportional to the absolute temperature of water.
