MYP Physics Topic 2.2 Phase Change Questionbank

True or False: According to the textbook, condensation is defined as the transition from gas to liquid when water vapor cools specifically below its saturation point.

On a phase diagram, what do the lines (boundaries) between the regions for solid, liquid, and gas represent?

When a substance undergoes a phase change from a liquid to a gas, which of the following best describes the change in the particles according to the particle model?

During a phase change like boiling, what happens to the energy added to the substance if the temperature remains constant?

Within Earth's energy balance, what is the thermodynamic effect of water evaporating from the ocean surface?

Conditions of temperature and pressure where two states of matter co-exist in equilibrium

Points where the substance ceases to exist

Regions where the substance undergoes chemical decomposition

The average speed of the particles in the vacuum of space

The particles themselves grow larger in size.

The particles change their chemical composition to form a new substance.

The particles lose kinetic energy and move closer together.

The spacing between particles increases and their arrangement becomes more random.

It is converted into chemical energy to form new substances.

It is used to increase the mass of the particles.

It is used by particles to overcome attractive forces.

It is destroyed during the transition.

It has no effect on the energy balance of the ocean
