Question

The temperature at which a liquid changes into its gaseous form is called ______

Answer 1

1. The boiling point is the temperature at which a liquid’s vapor pressure equals the external pressure surrounding the liquid.
2. The boiling point of a liquid depends on the atmospheric pressure. The boiling point is also referred to as the saturation temperature. The boiling point may be defined by the pressure at which the measurement was made.
3. In highlands such as hills and mountains, water boils at temperatures below normal boiling points because atmospheric pressure is below 1 atmosphere.
4. Therefore, the normal boiling point of water is 100 ° C (212F or 373K ).
   Hence, The temperature at which a liquid changes into its gaseous form is called the boiling point
