When the condenser is hotter than the evaporator, the coolant in the heat pipe condenses in a reservoir at the evaporator end.

When choosing sleeves, engines have specifications to how thick the cylinder walls should be to prevent overworking the coolant system.

When the EGR cooler failed, it would pump coolant through the engine.

When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition.

When this water level has been reached, inject steam until the temperature is that shown in Column Aj.

When this water level has been reached inject steam until the temperature is that shown in Column Aj.

When the eggs hatch, the tadpoles work themselves out of the foam and fall into the water below.

When the eggs hatch, he transports the tadpoles on his back, stuck there by a mucous secretion, to a temporary pool where he dips himself into the water and the tadpoles drop off.

When the Ark was borne by priests into the bed of the Jordan, water in the river separated, opening a pathway for the entire host to pass through ( Josh.

When tested, it approaches standards for potable water.

When the men were hunting on the water they wore waterproof parkas made from seal or sea-lion guts, or the entrails of bear, walrus, or whales.

When two monosaccharides undergo dehydration synthesis, water is produced, as two hydrogen atoms and one oxygen atom are lost from the two monosaccharides ' hydroxyl group.

When the pH of this solution rises, as a result of dilution by fresh water, these ions precipitate, forming " Yellow Boy " pollution.

When surfacing to breathe, the blue whale raises its shoulder and blowhole out of the water to a greater extent than other large whales, such as the fin or sei whales.

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 a hydrocarbon burns in oxygen, the reaction will only yield carbon dioxide and water.

When water percolates through limestone or other soluble carbonate rocks, it partially dissolves the rock and causes cave formation and characteristic stalactites and stalagmites and also forms hard 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 part of a forest is removed, the trees no longer evaporate away this water, resulting in a much drier climate.

When a Ghyben-Herzberg lens is fully formed, its floating nature will push a freshwater head above mean sea level, and if the island is wide enough, the depth of the lens below mean sea level will be 40 times the height of the water table above sea level.

When found on the beaches, Calophyllum often extends over the lagoon water and supports nesting red-footed boobies, as does Barringtonia asiatica.

When this happens, glucose remains in the filtrate, leading to the osmotic retention of water in the urine.

When the rains return and soils become wet, the osmotic gradient between the bacterial cells and the soil water causes the cells to gain water quickly.

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 temperature reached 32-degrees-F all protozoan activity ceased ; ;

When the pressure applied on a parcel of air decreases, the air in the parcel is allowed to expand ; as the volume increases, the temperature falls and internal energy decreases.

When compressed at room temperature to 7 GPa, α-berkelium transforms to the beta modification, which has a face-centered cubic ( fcc ) symmetry and space group Fmm.

When the partial pressure of is reduced, for example when a can of soda is opened, the equilibrium for each of the forms of carbonate ( carbonate, bicarbonate, carbon dioxide, and carbonic acid ) shifts until the concentration of in the solution is equal to the solubility of CO < sub > 2 </ sub > at that temperature and pressure.

When the temperature is low, the spring winds and closes the valve, which allows the fan to spin at about 20 % to 30 % of the shaft speed.

When a small increment of heat is gained by a calorimetric body, with small increments, of its volume, and of its temperature, the increment of heat,, gained by the body of calorimetric material, is given by

When the temperature decreases again, the rock contracts, causing pieces of the rock to break off.

When the moisture content evaporates during detonation, cooling occurs, which reduces the temperature of reaction.

When a system, for example, n moles of a gas of volume V at pressure p and temperature T, is created or brought to its present state from absolute zero, energy must be supplied equal to its internal energy U plus pV, where pV is the work done in pushing against the ambient ( atmospheric ) pressure.

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 the temperature rises beyond a certain point, called the Curie temperature, there is a second-order phase transition and the system can no longer maintain a spontaneous magnetization, although it still responds paramagnetically to an external field.

" When Groucho himself was on his deathbed, and a nurse came around with a thermometer, explaining that she wanted to see if he had a temperature, he responded, " Don't be silly — everybody has a temperature.

When heat is added to a thermal system, the change in entropy is the increase in mass-energy divided by temperature:

When this insulation is insufficient to maintain body temperature, they may resort to shivering -- rapid muscle contractions that quickly use up ATP, thus stimulating cellular metabolism to replace it and consequently produce more heat.

When the blade of an ice skate passes over the ice, the ice undergoes two kinds of changes in its physical state and a change in temperature due to kinetic friction and the heat of melting.

When the temperature drops below 50 ° F ( 10 ° C ), feeding, particularly with protein, is halted or the food can spoil in their stomachs, causing sickness.

When temperature is changed one of the phases grows, forming different morphologies depending on the temperature change.
