It forms the basis for the myriad of practical applications involving electric heating.

It may also involve mixing, heating or cooling, pressure cooking, fermentation, or combination with other food.

Baking, which involves heating to a higher temperature than does boiling, may destroy various essential nutrients.

This will usually involve heating of the chemical mix.

Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red.

Temperature shock involves cooling and heating of seawater by 3-5 C until spawning is induced.

The procedure involves volumetric heating of fibroids with real-time feedback.

They're also doing something called cryogenics, which involves heating and then cooling the blades to make them faster.

"Despite the simplicity of the process - basically it just involves heating in an oven - it is very accurate," he said.

Even a relatively routine workshop procedure involving heating is complicated by the fact that aluminium, unlike steel, will melt without first glowing red.
