The temperature at which a gas changes into a liquid is called the condensation point or dew point.

It's important to note that:

* The condensation point is specific to each substance. Different gases condense at different temperatures. For example, water condenses at 100°C (212°F) at standard atmospheric pressure.

* Condensation is influenced by pressure. The higher the pressure, the higher the condensation point.

* Condensation is a phase change, not a specific temperature. It's a process that happens over a range of temperatures, as the gas cools and its molecules slow down.
