Interpretation:

The change in entropy of a system if sugar cube is dissolved in a cup of tea is to be explained.

Concept introduction:

Entropy is the measurement of degree of disorder during a process. If a reaction is accompanied by increase in randomness then the value of entropy increases and vice-versa

Expert Solution & Answer

Answer to Problem 50SSC

The entropy of reaction will increase if sugar cube is dissolved in a cup of tea.

Explanation of Solution

Entropy gives the measurement of degree of randomness during a process.

When sugar cube is dissolved into a cup of tea, the particles of sugar which are in solid form are distributed into the particles of water molecules. As solids have less randomness and liquids have more randomness, randomness increases on adding sugar cube to cup of tea.
