The same is also true for an endothermic reaction, as in your example.

The reaction with Li is endothermic but does not consume the neutron.

It was probably endothermic and may have had fur."

As the enthalpy shows, the reaction is endothermic and this can be taken further advantage of in the industry.

The biggest being the move from endothermic to exothermic metabolisms.

So far all the reactions are overwhelmingly endothermic, except the electron attachment.

But a significant number of dissolution reactions are endothermic, so the picture is much more complicated than presented above.

If you mean changing a molecule into elements, decomposition is not always endothermic.

The endothermal effect at 118°C is due to dehydration.

Thereby, endothermal and exothermal reaction can be thermostated.

There was a spot where you, Joe Public, could press a button to "vote" on whether you thought dinosaurs were endothermal or not.

Endothermal ablation is a method of treatment for reflux disease in the GSV.

Endothermal upwelling, by which mild volcanic heat draws deep seawater up through the porous coral, may also contribute.

The reaction energy (the "Q-value") is positive for exothermal reactions and negative for endothermal reactions.

Although surgery will still be the best option for some, NICE says many patients should instead have either laser treatment or heat therapy (endothermal ablation).

Such endothermal activity is an example of the difficulty of consistent application of terms such as poikilothermy and homiothermy.

At low tetrahydrofuran mole fractions the deuterium oxide systems are more exothermal and at high tetrahydrofuran mole fractions more endothermal than the corresponding water systems.

In Hanoi, Dr. Kabnick also presented a lecture entitled "What We Know about Endothermal Ablation of the Saphenous Trunk," which was translated in advance for Vietnamese physicians.

"The ClosureFAST device has significantly improved endothermal ablation with a smooth, deliberate, controlled and much swifter technique," said Robert F. Merchant, M.D., of Reno, Nevada, who has been performing RF vein ablation since 1999.

The veins may cause no symptoms other than being unsightly, but the most recent advice for those in whom they cause aching, heaviness or skin changes is that they warrant treatment with a technique known as endothermal ablation (heat is used to seal off the faulty veins).

But in the 1970's, Dr. John H. Ostrom of Yale University and other scientists theorized that at least some dinosaurs were truly endothermal: capable of maintaining constant temperature by adjusting their metabolisms to warm or cool their own blood, compensating automatically for environmental temperature changes.

A positive sign means that the system uses heat and is endothermic.

They have a high metabolic rate and are considered endothermic.

Humans are endothermic creatures, which means they give off heat.

The dissolution of the salt in water is an endothermic process.

In both cases the change is endothermic, meaning that the system absorbs energy.

Being endothermic they use metabolic heat to raise body temperature.

Some direct evidence is available that ichthyosaurs too might have been endothermic.

However, many chemical and physical changes are now known which are endothermic.

From these results is the equilibrium given above an exothermic or endothermic process.

They naturally had a metabolism that was partially or completely endothermic.

Endothermic reactions with +ve enthalpy changes are often not spontaneous.

Heat can be provided for the endothermic calcination step either directly or indirectly.

The fundamental idea is that smaller endothermic animals have, relative to their mass, a larger body surface.

They seem to be endothermic bipeds, about our size.

As well, since the reaction is endothermic, a high temperature favors higher product yields.

So we can conclude that all feathered dinosaurs were endothermic.
