1. Abbr. BP
a. The temperature at which a liquid boils at a fixed pressure, especially under standard atmospheric conditions.
b. The temperature at which the vapor pressure of a liquid is equal to the ambient atmospheric pressure.
2. Informal

boiling point

n
1. (Chemistry) the temperature at which a liquid boils at a given pressure, usually atmospheric pressure at sea level; the temperature at which the vapour pressure of a liquid equals the external pressure
2. informal the condition of being angered or highly excited

boil′ing point`


n.
1. the temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid, equal to 212°F (100°C) for water at sea level. Abbr.: b.p.
2. the point beyond which one becomes visibly angry, outraged, or the like.
3. the point at which matters reach a crisis.

boil·ing point

(boi′lĭng)
The temperature at which a liquid changes to a vapor or gas. As the temperature of a liquid rises, the pressure of escaping vapor also rises, and at the boiling point the pressure of the escaping vapor is equal to that exerted on the liquid by the surrounding air, causing bubbles to form. Typically boiling points are measured at sea level. At higher altitudes, where atmospheric pressure is lower, boiling points are lower. The boiling point of water at sea level is 212°F (100°C); that of mercury is 673.84°F (356.58°C).

boiling point

The explicit relationship (23) between the saturation pressure [p.sub.sat] and the current amount of total gas mass fraction [x.sub.g] can be obtained considering the following:
A sudden pressure drop in the fluid causes the liquid to flash to vapor when the local pressure falls below the saturation pressure for the fluid being pumped.
A convenient alternative is to start with the pure-component fugacity at the saturation pressure, [f.sup.pure.sub.w] (T, [p.sup.sat]), which typically differs by only a small correction from the readily available pure-component vapor pressure [p.sup.sat](T) [[f.sup.pure.sub.w] (T, [p.sup.sat]) = [[phi].sup.sat][p.sup.sat], where [[phi].sup.sat.sub.w](T, [p.sup.sat]), the fugacity coefficient at saturation, is 1 for an ideal gas and typically slightly less than 1 for low and moderate pressures].
In the previous energy balance, the air mass in the VV and the VVPSS has been neglected, due to its limited amount and energy contribution, if an air ingress is excluded: therefore, the initial ST pressure [P.sub.ST,0] is the water saturation pressure only.
Figure 1 shows saturation pressure temperature relationships for R-507 (an azeotrope), R-404A (a low-glide zeotrope) and R-407A (a high-glide zeotrope).
In vacuum cooling, the pressure in vacuum chamber to product initial temperature corresponding saturation pressure, the product of water evaporated.
This tends to continue until either the condenser and evaporator pressures have equalized or all two-phase refrigerant has migrated from the warmer condenser (higher saturation pressure) to the cooler evaporator (lower saturation pressure).
The saturation pressure is at the lowest value investigated, whereas the temperature and the release gradient of the pills demonstrate the initial point of the research plan.
The pipe material and wall thickness were kept constant in both tests--four pipe joints with varying wall thickness or material strength for each test, and the saturation pressure of the C[O.sub.2] adjusted by controlling the fluid temperature to achieve fracture arrest or propagation.
where [partial derivative]w/[partial derivative][phi] is the moisture storage capacity (kg/[m.sup.3] %), [partial derivative]H/[partial derivative]T is the heat storage capacity of the moist building material (J/kg), w is the moisture content (kg/[m.sup.3]), [lambda] is the thermal conductivity (W/m x K), [D.sub.[phi]] is the liquid conduction coefficient (kg/m x s), [[delta].sub.p] is the water vapour permeability (kg/m x s x Pa), [h.sub.v] is the evaporation enthalpy of the water (J/kg), [p.sub.sat] is the water vapour saturation pressure (Pa), T is the temperature (K), and [phi] is the relative humidity (%).
