Which of the following apply to diffusion. Select all that apply. Solids can diffuse in liquids. Liquids can diffuse in liquids.
e-lub [12.9K]

Correct answers are:

  • Solids can diffuse in liquids. Think of a sugar cube sitting at the bottom of a cup of tea.
  • Liquids can diffuse in liquids. Think of a drop of food colouring in water
  • It is the process of intermingling atoms from one substance into another.

The other answers are <em>incorrect</em> because:

  • Gas molecules are far apart and diffuse rapidly.  
  • A solid can diffuse into another solid. Pure lead can diffuse into gold, and pure gold can diffuse into lead.

Answer:

5446.8 J

Explanation:

From the question given above, the following data were obtained:

Mass (M) = 50 g

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Specific heat capacity (C) = 0.89 J/gºC

Heat (Q) required =?

Next, we shall determine the change in the temperature. This can be obtained as follow:

Initial temperature (T₁) = 70 °C

Final temperature (T₂) = 192.4 °C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 192.4 – 70

ΔT = 122.4 °C

Finally, we shall determine the heat required to heat up the block of aluminum as follow:

Mass (M) = 50 g

Specific heat capacity (C) = 0.89 J/gºC

Change in temperature (ΔT) = 122.4 °C

Heat (Q) required =?

Q = MCΔT

Q = 50 × 0.89 × 122.4

Q = 5446.8 J

Thus, the heat required to heat up the block of aluminum is 5446.8 J
