When values of temperature derived with this instrument were compared with the accepted values associated with liquid helium-4 vapor pressures, differences of about 10 and 7 millidegrees respectively were found.

When the working liquid is water and the bain-marie is used at sea level, the maximum temperature of the material in the lower container will not exceed 100 degrees Celsius ( 212 F ), the boiling point of water at sea level.

] When he had done eating, he usually took a Kind of Chocolate, made after the Manner of the Country, that is, the Substance of the Nut beat up with the Mill till the Cup was filled more with Froth than with Liquor ; after which he used to smoak Tobacco perfum'd with liquid Amber.

When a multi-component liquid is heated, the vapor pressure of each component will rise, thus causing the total vapor pressure to rise.

When the total vapor pressure reaches the pressure surrounding the liquid, boiling occurs and liquid turns to gas throughout the bulk of the liquid.

When the process feed has a diverse composition, as in distilling crude oil, liquid outlets at intervals up the column allow for the withdrawal of different fractions or products having different boiling points or boiling ranges.

When the process of escape and return reaches an equilibrium, the vapor is said to be " saturated ," and no further change in either vapor pressure and density or liquid temperature will occur.

When cooked in broth, gluten absorbs some of the surrounding liquid ( including the taste ) and becomes firm to the bite.

When fully chilled, the most common ratios of gelatin to liquid ( as instructed on commercial packaging ) usually result in a custard-like texture which can retain detailed shapes when cold but melts back to a viscous liquid when warm.

When a pipette injects a liquid onto a solid, the liquid will form some contact angle.

When no voltage is applied to a TN liquid crystal cell, polarized light passes through the 90-degrees twisted LC layer.

When no voltage is applied, the liquid crystals remain perpendicular to the substrate creating a black display between crossed polarizers.

When voltage is applied, the liquid crystals shift to a tilted position allowing light to pass through and create a gray-scale display depending on the amount of tilt generated by the electric field.

When viewed under a microscope using a polarized light source, different liquid crystal phases will appear to have distinct textures.

When physical chemist Richard Williams applied an electric field to a thin layer of a nematic liquid crystal at 125 ° C, he observed the formation of a regular pattern that he called domains ( now known as Williams Domains ).

When an external electric field is applied to the liquid crystal, the dipole molecules tend to orient themselves along the direction of the field.

When an electric field is applied to the LC layer, the long molecular axes tend to align parallel to the electric field thus gradually untwisting in the center of the liquid crystal layer.

When the Justice Society's forced attempt to stop them by sending Hawkman and Captain Marvel against them met with failure and resulted in Superman and Batman briefly infiltrating the White House, Luthor, in an enraged and desperate gambit after Superman's rapid defeats of his plans, used a variant combination of the " super-steroid " Venom ( a chemical associated with the Batman villain Bane ), liquid synthetic Kryptonite, and an Apokoliptian battlesuit to fight Superman directly.

When the material is cooled, this domain alignment structure spontaneously returns, in a manner roughly analogous to how a liquid can freeze into a crystalline solid.

When measuring vacuum, the working liquid may evaporate and contaminate the vacuum if its vapor pressure is too high.

When measuring liquid pressure, a loop filled with gas or a light fluid can isolate the liquids to prevent them from mixing but this can be unnecessary, for example when mercury is used as the manometer fluid to measure differential pressure of a fluid such as water.

When in contact with one of the electrodes in a fuel cell, this platinum increases the rate of oxygen reduction to water, either to hydroxide or hydrogen peroxide.

When considering fuel economy in automobiles two measures are commonly used – miles per gallon ( mpg ), and litres per 100 km.

A Power stroke: When the piston reaches a point just before top dead center, the spark plug ignites the fuel mixture.

When the piston moves further down and the cylinder doesn't have anymore gases, fuel mixture starts to flow to the combustion chamber and the second process of fuel compression starts.

Operation: When the piston moves from bottom dead center ( BDC ) to top dead center ( TDC ) the fresh air and fuel mixture enters the crank chamber through the intake port.

When using lower grade fuel, or worn engine the oil change interval has to shorten accordingly.

When Macduff learns of the murders of his wife and child, Malcolm consoles him unsympathetically with encouragement to take the news in “ manly ” fashion and use it to fuel his hatred of Macbeth.

When the bottle smashes on impact, the ensuing cloud of petrol droplets and vapour ignites, causing an immediate fireball followed by a raging fire as the remainder of the fuel is consumed.

When increasing concern within the company over the pricing and availability of fuel during the oil crisis of the 1970s became an issue of contention, smaller engines were considered in the interest of fuel economy.

When burned with oxygen, hydrogen gives the highest specific impulse of any commonly used fuel: around 450 seconds, compared with up to 350 seconds for kerosene.

When the energy gradient created by unleashing this fraction of the stored fuel was exhausted, the beings would enter a state of zero-energy-consumption until the universe cooled.

When they run out of thruster fuel, the satellites are at the end of their service life as they are no longer able to keep in their allocated orbital position.

When the weight of the payload and fuel are considered together, it is known as the " useful load fraction ".

When the bomb detonated, the casing would contain the explosion long enough for mechanical shock to heat and compress the fusion fuel, and for fission neutrons to ignite nuclear fusion.

When driving on a highway, convoys are also useful to conserve fuel by drafting.

When carburetors are used in aircraft with piston engines, special designs and features are needed to prevent fuel starvation during inverted flight.

When the step-up rod is lowered into the main jet, it restricts the fuel flow.

When the step-up rod is raised out of the jet, more fuel can flow through it.

When the throttle is rapidly opened, airflow through the carburetor increases immediately, faster than the fuel flow rate can increase.

When the engine is cold, fuel vaporizes less readily and tends to condense on the walls of the intake manifold, starving the cylinders of fuel and making the engine difficult to start ; thus, a richer mixture ( more fuel to air ) is required to start and run the engine until it warms up.
