Changes of State

Flashcards about changes of state

What does the amount of energy needed to change state depend on?

The amount of energy needed to change state from solid to liquid and from liquid to gas depends on this.

What is the relationship between the strength of forces and the melting and boiling point?

The stronger the forces between the particles, the higher these two points of the substance.

What type of change is changing states?

A change of state.

What are intermolecular forces?

Forces of attraction between neighboring molecules.

What is melting?

When a solid changes into a liquid.

What happens to the particles during melting as they absorb heat/thermal energy and it is transformed into kinetic energy?

The particles vibrate more and start to move/flow

What characterizes the temperature at which melting occurs?

Happens at a specific temperature, known as the melting point
