Unit 8 States of Matter & Intermolecular Forces

Front

What is sublimation?

Back

The process where a solid changes directly into a gas without passing through the liquid phase, often occurring at low pressure and temperature.

Front

What is the strongest intermolecular force of attraction in polar molecules?

Back

Dipole-Dipole interactions, which occur between the positive end of one polar molecule and the negative end of another.

Front

What does Boyle's Law state?

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

How does altitude affect boiling points?

Back

As altitude increases, atmospheric pressure decreases, leading to a decrease in boiling points.

Front

What is standard pressure in atmospheres?

Back

1 atm, which is the average atmospheric pressure at sea level.

Front

Define intermolecular forces.

Back

Forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

What is the phase diagram of a substance?

Back

A graphical representation showing the phases of a substance at different temperatures and pressures.

Front

What happens during melting?

Back

The process where a solid turns into a liquid as it absorbs heat.

Front

What is condensation?

Back

The process where a gas turns into a liquid as it loses heat.

Front

What is the significance of Avogadro's Law?

Back

It states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules.
