Answer #1

Among three different phases of a substance,

The decreasing order of stability is : Solid > Liquid > Gas

The decreasing Energy order is : Gas > liquid > Solid

Reason: In solid state the constituents are closely paked in definite order, hence they do not find space to travel from one place to other, thus having less energy and more stable in state.

The exact reverse is true for Gases. They do not have a definite shape, and the distance among the constituents is too large, Hence having more energy and less stability.

A tube holds a monatomic substance with equal amounts of liquid and gas at equilibrium. A student analyses the problem and says, “According to the Particle Model, the liquid phase has more thermal energy than the gas phase.” Another student digests this and then states, “This is incongruent with the Three Phase Model, which states that a gas has more energy than a liquid.” Which of the statements is/are true? Which is/are false? Why?

Why is there a change in enthalpy when water is a liquid in the products (as opposed to a gas)? a. Because phase changes require or release heat. b. Because there is a chemical change associated with phase changes, which changes the enthalpy. c. Because liquid water is less stable than gaseous water. d. This is false – the enthalpy does not depend on the phases of the reactants and the products.
