When the group's ship suffers a warp core breach and is going to explode, he offers to beam them aboard his ship so they can survive, but they refuse and tell him to move off to a safe distance which he does.

When the temperature and pressure in the core become sufficient to ignite helium fusion, a helium flash will occur if the core is largely supported by electron degeneracy pressure ( stars under 1. 4 solar mass ).

When the ski was torqued, the position of the aluminum sheets above and below the axis of rotation required them to slide sideways relative to the core, something that was resisted by the glue along the entire surface of the sheet.

When a voltage is applied to the primary winding, a small current flows, driving flux around the magnetic circuit of the core.

When an atom is probed by an external mechanism, such as a photon or a beam of electrons with energies in the range of 2 keV to 50 keV, a core state electron can be removed leaving behind a hole.

When slalom skiing is done properly, the skier will experience numerous isometric contractions ( good training for core muscles ), and extreme upper body torque, making it a good form of exercise.

When the ski was rotated on-edge, the aluminum sheets prevented the wooden core from twisting longitudinally, and kept much more of the ski's edge firmly pressed into the snow.

When a light ray is incident from a medium of refractive index n to the core of index n < sub > core </ sub > at the maximum acceptance angle, Snell's law at the medium – core interface gives

When he and Lando reach the Death Star's core, Wedge destroys the power regulator on the core's northwest tower, while Lando destroys the core itself.

When Nepos made the mistake of appointing the untrustworthy Orestes as his magister militum, his lack of a western core of support came back to haunt him.

When the Russians expanded into Transbaikalia ( eastern Siberia ) in 1609, the Cossacks found only a small core of tribal groups speaking a Mongol dialect called Buryat and paying tribute to the Khalkhas.

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 this water level has been reached, inject steam into the wheel until the temperature reaches that shown in Column B of Table 2.

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 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 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 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.
