The old mercury-vapor lamp in the parking lot cast a cold, bluish glow all night.

The old sodium vapor lamp on the corner bathed the street in a warm yellow haze.

Saturation vapor pressures over different salt solutions were measured to assess their hygroscopicity.

Saturated vapor pressures vary significantly with temperature and must be considered when designing refrigeration systems.

The old stadium relied on mercury-vapor lamps to illuminate night games, but they were costly to maintain.

The researchers compared the equilibrium vapor pressures of several organic solvents at different temperatures to improve the accuracy of their phase equilibrium model.

The city replaced the old streetlights with energy-efficient sodium vapor lamps to cut down on maintenance and costs.
