Which statement describes a system that consists of sugar crystals dissolving in water?

the system becomes more ordered and has an increase in entropy.
the system becomes more ordered and has a decrease in entropy.
the system becomes more disordered and has an increase in entropy.
the system becomes more disordered and has a decrease in entropy.

Answer : The correct statement is, The system becomes more disordered and has an increase in entropy.

Explanation :

Entropy : It is defined as the measurement of randomness or disorderedness in a system.

The order of entropy will be,

As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.

As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.

Here, a system consist of sugar crystal (solid) when it dissolve in water they dissociates into ions that means entropy will be increases due to the increase in the disorderedness.

Hence, the correct statement is, The system becomes more disordered and has an increase in entropy.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
