Dew Point
Definition
The temperature below which condensation can occur from air of a given moisture content. Condensation can form when a surface is sufficiently cool relative to surrounding air’s moisture conditions. Temperature and humidity histories are relevant.
- Context
- Environmental conditions
For example, moving a cold item into moist warm air can create condensation conditions that a later dry-room reading does not reconstruct.
A single later room reading does not establish earlier condensation on an exhibit. Storage and packaging effects require their actual conditions.
