Compare how entropy changes for the following two systems:


System A: A gas and a solid react to form a new solid product.


System B: Rubbing alcohol evaporates on the skin

Respuesta :

In system A: A gas and a solid react to form a new solid product. The system entropy decreases.

In System B: Rubbing alcohol evaporates on the skin. Liquid alcohol is converted to gas by evaporation. So the system entropy increases.

What is Entropy?

Entropy is a thermodynamic quantity measure the degree of disorder of a certain system.

Gases have larger entropy compared to liquids and which is larger than solids.

  • System A: When a gas convert to a solid, its entropy decreases because solids have less energy and entropy than solids.
  • So, in system A: A gas and a solid react to form a new solid product. The system entropy decreases.
  • System B: Any chemical reaction that increases the number of gas molecules also increases entropy.
  • So, in System B: Rubbing alcohol evaporates on the skin. Liquid alcohol is converted to gas by evaporation. So the system entropy increases.

Answer:

System A: The entropy decreases due to the solid having fewer moving particles than the gas .

System B: There is an increase in entropy. The change in the state of a liquid to a gas is an increase in entropy (disorder) because the particles of a gas are moving faster and forming more random arrangements than they are in the more condensed liquid state.
