I. adjective
COLLOCATIONS FROM CORPUS
■ NOUN
conductivity
▪
The most obvious differences are the lower density and thermal conductivity of plastics compared with glass.
▪
The relatively static lattice in a diamond ensures that the scattering is at a minimum and the thermal conductivity is exceptionally good.
▪
In fact, at room temperature a diamond has a thermal conductivity about six times higher than a piece of copper.
▪
This high thermal conductivity gives diamond a small but useful role in the semiconductor industry.
energy
▪
The thermal energy extracted from the reactor would boil a propellant liquid.
▪
High-temperature electrolysis uses a large amount of electrical and thermal energy .
▪
Near absolute zero, however, molecules have much less thermal energy .
▪
Such molecules are in general less abundant than ground state molecules, because of the Boltzmann distribution of thermal energy .
▪
For example, when coal is burned, chemical energy is transformed into thermal energy.
▪
Rocket engineers speak loosely of thermal energy being converted into kinetic energy in the engine bell.
▪
Consequently, more thermal energy is required before the crystal becomes unstable, and T m is raised.
▪
Any thermal energy is shared by the whole lattice rather than a single nucleus.
expansion
▪
It could make or break with vibration or thermal expansion as the machine warmed up.
▪
So it is difficult to estimate thermal expansion as a result of surface warming.
▪
In the latter case, thermal expansion of the wire proportional to the heating is sensed by mechanical means.
▪
The occurrence of scrub and forest fires provides another mechanism whereby rocks can be subjected to significant thermal expansion and contraction.
▪
Some of the illustrations of shattered pebbles attributed to thermal expansion and contraction are of flint and quartzites.
▪
The importance of thermal expansion , the third mechanism of salt weathering, has yet to be fully evaluated.
insulation
▪
Softboard has a spongy texture, which gives it good sound and thermal insulation properties.
▪
If extra thermal insulation is required flat insulation panels can be laid underneath the profiled Rockwell insulation panels.
▪
Grants may also be available for thermal insulation , or repairs to properties in clearance areas.
▪
The detailed design of the thermal insulation and of the technical elements of the house will be described in the following chapters.
▪
In any case, high-vacuum equipment is needed to ensure adequate thermal insulation .
▪
The ability to operate at these temperatures is advantageous, because liquid nitrogen is cheap and the devices need less thermal insulation .
▪
The remaining third covered anything from thermal insulation and heating through to fire safety and maintenance problems.
▪
The biggest item would be thermal insulation - £5 billion.
EXAMPLES FROM OTHER ENTRIES
▪
thermal radiation
▪
Runners were given thermal blankets to prevent heat loss at the end of the race.
▪
Wear thermal underwear, hat, and gloves while skiing.
EXAMPLES FROM CORPUS
▪
But as the temperature of the material rises thermal vibrations cause the pairs to break apart and superconducting ceases.
▪
For example, when coal is burned, chemical energy is transformed into thermal energy.
▪
Gas is derived primarily from the thermal maturation of organic master, principally plant remains, in a variety of sediments.
▪
It's time to get your thermal vest on, never mind skates.
▪
It seems far more likely that it is this thermal activity that sweeps insects high into the sky on fine days.
▪
One tonne of marijuana has a thermal value of 2.7 barrels of oil.
▪
The thermal shock is, by comparison, bliss.
▪
The islands are also renowned for their thermal springs and sulphur baths.
II. noun
EXAMPLES FROM CORPUS
▪
Great granite fortresses sprang up in the misty vales and from them Dragon Princes rode the thermals over sullen volcanoes.
▪
In general, the same clothing was used underneath - Rhoval/Modal thermals and Polartec 200 fleece.
▪
In this way it is possible to use the lift low down with safety, provided that the thermals are not too turbulent.
▪
Soon the kites were circling the thermals, a great helix of wide-winged birds sailing the vectors in sweeping corkscrew spirals.
▪
The former occurs both within the thermals and in the slowly downward drifting cold fluid between the thermals.
▪
This creates a breathing space between inner clothes and the waterproof outer skin; important when only thermals are being worn underneath.
