A. A diagram showing the effects of temperature and pressure on  phase

Explanation:

A phase diagram is a diagram that shows the effects of temperature and pressure on phase.

  • A phase diagram shows how different substances are transformed from one form to another.
  • The transformation is an interplay between pressure and temperature.
  • The phase graph represents physical state changes.
  • A phase change is made up of pressure on the y-axis and temperature on the x - axis.

Which of the following does NOT involve a change of state? a. pouring water into a vacuum-insulated bottle b. sublimation of dry
Elena L [17]
<h2> The correct option is (a).</h2>

Explanation:

  • There is no change of state in pouring water into a vacuum insulated bottle as the vacuum created inside the bottle only reduces the time limit for the transfer of heat by conduction and convection.
  • It helps the content filled in the bottle to be hot and cool for a longer time.

Hence, option (a) is correct.

Rest of the options (b), (c), (d), (e) is not correct because of the following reasons:

  • In the sublimation of dry ice, the dry ice (solid-state) is changed to the vapour form.
  • In the freezing of water, the liquid state is changed to solid-state.
  • During the vaporization of alcohol, the liquid state is changed to the vapour form.
  • During the melting of ice, the solid-state is changed to the liquid state.
