C1: 5.3 Intermolecular Forces

Front

What term describes a liquid that flows very slowly?

Back

High viscosity.

Front

What can be inferred about a substance that remains in the gas phase down to –150˚C?

Back

The intermolecular forces between particles in this substance are weak.

Front

What does it indicate if a liquid allows a marble to fall to the bottom very quickly?

Back

The intermolecular forces within the liquid must be weak.

Front

What is true about a substance with strong intermolecular forces?

Back

It has low volatility.

Front

If solid X melts at 175˚C and solid Y melts at 800˚C, what can be concluded?

Back

Y has stronger intermolecular forces than X.

Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting their physical properties.

Front

What is the relationship between intermolecular forces and boiling point?

Back

Stronger intermolecular forces generally lead to higher boiling points.

Front

What is viscosity?

Back

A measure of a fluid's resistance to flow.

Front

How do intermolecular forces affect the state of matter?

Back

Stronger intermolecular forces can keep particles in a solid or liquid state.

Front

What is volatility?

Back

The tendency of a substance to vaporize; low volatility means it does not vaporize easily.
