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
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.

- Speaking of composite materials, indicate the correct option:(A). Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A).
