An example of liquid to gas would be water turning to steam without a change in temperature. This is known as vaporization.
The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
To change from a gas into a liquid you must cool the substance. For example: water vapour to water.

Phase change
A flat line on a phase diagram indicates a phase transition occurring at a constant temperature and pressure. For example, a flat line on a gas-liquid equilibrium graph means that the substance is transitioning between the gas and liquid phases without changing temperature or pressure.
During equilibrium between liquid and gas phases, the substance undergoes both evaporation (liquid to gas) and condensation (gas to liquid) processes simultaneously. The rate of evaporation equals the rate of condensation, leading to no net change in the amount of liquid or gas over time. This dynamic equilibrium is maintained as long as the system's temperature and pressure remain constant.
