text_A: .001% of water can be found in forms of gas.
text_B: In physics a vapor -LRB- American -RRB- or vapour -LRB- British -RRB- is a substance in the gas phase at a temperature lower than its critical temperature , which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature .. gas. gas. temperature. temperature. critical temperature. critical temperature. condensed. condensation. liquid. liquid. pressure. pressure. A vapor is different from an aerosol .. aerosol. aerosol. An aerosol is a suspension of tiny particles of liquid , solid , or both within a gas .. gas. gas. liquid. liquid. aerosol. aerosol. For example , water has a critical temperature of 647 K , which is the highest temperature at which liquid water can exist .. temperature. temperature. critical temperature. critical temperature. liquid. liquid. In the atmosphere at ordinary temperatures , therefore , gaseous water -LRB- known as water vapor -RRB- will condense into a liquid if its partial pressure is increased sufficiently .. liquid. liquid. pressure. pressure. atmosphere.

When this is true , the two phases will be in equilibrium , and the gas-partial pressure will be equal to the equilibrium vapor pressure of the liquid -LRB- or solid -RRB- .. gas. gas. liquid. liquid. pressure. pressure. partial pressure. partial pressure. vapor pressure. vapor pressure
