When sufficiently accurate and complete measurements are available, it will be possible to set limits on the thermal and electrical characteristics of the surface and subsurface materials of the moon.

When energy is in a form other than thermal energy, it may be transformed with good or even perfect efficiency, to any other type of energy, including electricity or production of new particles of matter.

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

When in thermal equilibrium, then, it is seen that the lower energy state is more populated than the higher energy state, and this is the normal state of the system.

When the core temperature reaches about, the thermal energy dissociates the H < sub > 2 </ sub > molecules.

When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy.

When the turbine is used solely for shaft power their thermal efficiency is around the 30 % mark.

When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermal resistance, can be described.

When thermal resistances occur in series, they are additive.

When a material undergoes a phase change from solid to liquid or from liquid to gas the thermal conductivity may change.

# When the drums are heated by hard braking, the diameter of the drum increases slightly due to thermal expansion, this means the brakes shoes have to move farther and the brake pedal has to be depressed further.

When used well and combined with passive solar design, thermal mass can play an important role in major reductions to energy use in active heating and cooling systems.

When temperatures fall at night, the walls re-radiate the thermal energy back into the night sky.

When molecules are in thermal motion, as they are in the gas and liquid phase, the electrostatic force is averaged out to a large extent, because the molecules thermally rotate and thus probe both repulsive and attractive parts of the electrostatic force.

When capsaicin is present, it alters the conformation of the SERCA, and thus reduces the ion movement ; as a result the ATP energy ( which would have been used to pump the ions ) is instead released as thermal energy.

When the sample and reference are heated identically phase changes and other thermal processes cause a difference in temperature between the sample and reference.

When a body is heated at constant temperature by thermal radiation in a microwave field for example, it may expand by an amount described by its latent heat with respect to volume or latent heat of expansion, or increase its pressure by an amount described by its latent heat with respect to pressure.

When conventional brakes are used, 100 % of the kinetic energy lost is converted to thermal energy, and dissipated in the form of heat.

When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, at which point they are in thermal equilibrium.

When the pilot chooses to pull up to enter a thermal or to dive to exit a sink area, an uncompensated variometer will include the change in altitude due to the change in velocity in its read-out, thus marring the airmass ' climb or sink rate.

When the glider circles to thermal, the pilot needs to know the glider's vertical speed instead of that of the air mass.

When a planet generates a significant amount of heat internally, such as is the case for Jupiter, convection in the atmosphere can transport thermal energy from the higher temperature interior up to the surface.

When the CPU is idle, it will draw far less than the typical thermal power.

When such a processor reaches a temperature level deemed too high for safe operation, the thermal control circuit activates, automatically decreasing the clock and CPU core voltage until the temperature has returned to a safe level.

When reconstructing the data, owing to the evaporation of successive layers of material from the sample, the lateral and in-depth reconstruction values are highly anisotropic.

When heat and pressure are applied to the layers, a chemical reaction ( polymerization ) transforms the layers into a high-pressure thermosetting industrial laminated plastic.

When P and N-doped layers are placed in contact, diffusion ensures that electrons flow from high to low density areas: That is, from the N to the P side.

When stacking one of these layers on top of another, the atoms are not directly on top of one another — the first two layers are identical for hcp and fcc, and labelled AB.

When many partially transparent layers need to be composited together, it is worthwhile to consider the algebraic properties of compositing operators used.

When all the layers were finished, they were combined into one image using a large process camera.

When these stones were removed, the workmen found inside the remains of an oak coffin the complete skeleton of an individual entirely enclosed in two layers of thin lead, with a shroud of cloth of gold over it.

When various layers are used, soles may consist of an insole, midsole, and an outsole.

When reflection occurs from thin layers of material, internal reflection effects can cause the reflectance to vary with surface thickness.

When a low stratiform cloud contacts the ground, it is called fog, although radiation and advection types of fog do not form from stratus layers.

When the retrieved representations do not sufficiently resolve newly arrived patterns, evaluating persists, engaging higher layers of the cortex in an ongoing pursuit of resolution.

When reelin is absent, like in the mutant reeler mouse, the order of cortical layering becomes roughly inverted, with younger neurons finding themselves to be unable to pass the settled layers.

When a river breaks its banks and floods, it leaves behind layers of rock and mud.

When removed from the oven, the layers of baked dough remain separated inside the deflated pita, which allows the bread to be opened into pockets, creating a space for use in various dishes.

When it reaches the edge of the form, the bed load rolls over the edge, and builds up in steeply angled layers over the top of the bottomset beds.

" When finished, the dome was three layers: an inner dome with an oculus, a decorative outer wood dome covered in lead roofing, and a structural brick cone in between.

When forming this bird base, make sure to crease the triangle at the center corner through all layers.

When exceeding the Eddington luminosity, a star would initiate a very intense continuum-driven stellar wind from its outer layers.

When core collapse occurs in a sufficiently massive star, the explosion energy is insufficient to expel the outer layers of the star and it will collapse into a black hole without producing a visible supernova outburst.

To prevent roof tears like those that occurred in its first years of service, the Metropolitan Sports Facilities Commission adopted a twofold strategy: When snow accumulation was expected, hot air was pumped into the space between the roof's two layers.

When the tide comes in, they move into the upper layers of sand so as to be able to feed on the plankton and detritus that washes over them with each wave.

When geological deposits of mud are formed in estuaries the resultant layers are termed bay muds.

When used for dimensionality reduction purposes, one of the hidden layers in the network is limited to contain only a small number of network units.
