Front

What is the definition of STP in chemistry?

Back

Standard Temperature and Pressure, defined as 0°C (273.15 K) and 1 atm pressure.

Front

What is the relationship between temperature and vapor pressure?

Back

As temperature increases, vapor pressure increases.

Front

Define intermolecular forces.

Back

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

Front

What is the effect of increasing intermolecular forces on boiling point?

Back

Increasing intermolecular forces generally leads to a higher boiling point.

Front

What is the principle behind paper chromatography?

Back

Separation of substances based on their different affinities to the stationary phase and the mobile phase.
